## What is the current behavior?
<!-- Please describe the current behavior that you are modifying. -->
There are two issues causing Ionic Vue apps to not behave as intended
with certain versions of Vue:
1. In Vue 3.3 a [breaking change
shipped](https://github.com/vuejs/core/issues/9916) that changes the
default behavior of the `watch` inside of IonRouterOutlet to be a
shallow watcher instead of a deep watcher. This caused the router outlet
to not consistent re-render. While the change was later reverted by the
Vue team, they expressed that the change [may re-land in a future minor
release](https://github.com/vuejs/core/issues/9965#issuecomment-1875067499).
As a result, we will need to account for this inside of Ionic.
2. In Vue 3.2 a [custom elements improvement
shipped](https://github.com/vuejs/core/blob/main/changelogs/CHANGELOG-3.2.md#3238-2022-08-30)
that changed how custom elements are referred to in VNodes.
## What is the new behavior?
<!-- Please describe the behavior or changes that are being added by
this PR. -->
- The affected `watch` call now is now explicitly a deep watcher. This
change is backwards compatible as well as forward compatible with
upcoming Vue changes.
- Updated IonTabs to account for the new VNode behavior for custom
elements. Ionic still supports version of Vue that do not have this
improvement, so we need to account for both behaviors for now. I also
added a tech debt ticket to remove the old checks when we drop support
for older versions of Vue.
- Updated E2E test dependencies. During this update some of our tests
needed to be updated to account for newer versions of Vue/Vitest.
Overall I was able to simplify a lot of our tests as a result.
I plan to add renovatebot to these E2E test apps, but I will handle that
in a separate PR.

Dev build: `7.6.6-dev.11705526292.1bc0acb5`
Note: Both of the issues cause tests to fail when using the latest
dependencies in the Vue E2E test app. However, I need to use the latest
dependencies so I can demonstrate that my changes do fix the reported
issues. As a result, I have both fixes in the same PR.

## What is the current behavior?
<!-- Please describe the current behavior that you are modifying. -->
It's not possible to pass props that are not camelCase to the `IonNav`
component.
## What is the new behavior?
<!-- Please describe the behavior or changes that are being added by

- It is now possible to set a props with kebab-case instead of camelCase
(for example, `root-params` instead of `rootParams`)

⚠️ This is my first PR for ionic so I hope I didn't miss important steps
into the process. I also checked on my project that the fix is working
well. Thank you! 🙂

The overlay implementation in Vue only checks for truthy
`keepContentsMounted` values. When setting this prop as an attribute,
the value of it is `''` which is falsy. As a result, content does not
get mounted.
One of Vue's ESLint rules states that this should be supported:
https://eslint.vuejs.org/rules/prefer-true-attribute-shorthand.html
Part of the issue may also be that Vue does not know the type of this
property and so it assume "any":
> The shorthand form is not always equivalent! If a prop accepts
multiple types, but Boolean is not the first one, a shorthand prop won't
pass true.
## What is the new behavior?
<!-- Please describe the behavior or changes that are being added by
this PR. -->
- The overlay wrapper now checks for `''` values. If
`keepContentsMounted === ''` then the inner contents will be mounted
because this means the prop is being set using the attribute shorthand.

## What is the current behavior?

Passing multiple elements in to an inline modal causes `.ion-page` to
not get set. This causes content to get pushed off the bottom of the
modal equal to the height of the header. React has some special CSS that
prevents this:
eb2772c0ce/packages/react/src/components/createInlineOverlayComponent.tsx (L137-L140)
However, I think this should be delegated to `.ion-page` instead so the
behavior is consistent across frameworks. For example, Angular uses
`.ion-page`:
eb2772c0ce/angular/src/directives/overlays/modal.ts (L82)
## What is the new behavior?
<!-- Please describe the behavior or changes that are being added by
this PR. -->
- Inline overlays in Ionic React and Ionic Vue wrap child content in
`.ion-delegate-host.ion-page`.
- Removed the custom flex styles from Ionic React as `.ion-page` has its
own styles.
