## What is the current behavior?
<!-- Please describe the current behavior that you are modifying. -->

Watchers in Stencil are constructed sometime between `connectedCallback`
and `componentDidLoad`. If a property is set/changed during that time it
is possible for the callback associated with the watcher to not fire
because the watcher has not been setup yet. This is most often with
`dist-custom-elements` and frameworks such as Angular when using a
binding (i.e. `[trigger]` instead of `trigger`)

## What is the new behavior?
<!-- Please describe the behavior or changes that are being added by
this PR. -->

- The trigger callback associated with the watcher is manually called in
`componentDidLoad` for each overlay.

## Does this introduce a breaking change?

- [ ] Yes
- [x] No

<!-- If this introduces a breaking change, please describe the impact
and migration path for existing applications below. -->

screenshots of how the component looks before and after the change. -->


Dev build: `7.5.5-dev.11699974376.13a15397`

Note: This is a timing related bug due to a behavior in Stencil, so I
did not write automated tests. However, I manually verified that this
issue a) reproduces on `main` and b) is fixed with this dev build for
each overlay component.
