Issue number: resolves #29211 --------- <!-- Please do not submit updates to dependencies unless it fixes an issue. --> <!-- Please try to limit your pull request to one type (bugfix, feature, etc). Submit multiple pull requests if needed. --> ## What is the current behavior? <!-- Please describe the current behavior that you are modifying. --> In https://github.com/ionic-team/ionic-framework/pull/28861 I fixed a bug that caused `.popover-viewport` to have `overflow: hidden`. In reality, this code should have always applied but due to an incorrect selector it never did. As it turns out in https://github.com/ionic-team/ionic-framework/issues/29211, some developers were relying on the broken behavior to build their applications. In particular, developers were using `ion-popover` without an `ion-content`. The linked change made it so that using popovers without `ion-content` were not scrollable. After talking with @mapsandapps we think it makes sense to officially support this behavior. We support using [modals without `ion-content`](https://ionicframework.com/docs/api/modal#custom-dialogs), and we could not think of a reason to not support the same use case for popover. ## What is the new behavior? <!-- Please describe the behavior or changes that are being added by this PR. --> - If the `.popover-viewport` element has a child content then `.popover-viewport `will not be scrollable. - If the `.popover-viewport` element does not have a child content then `.popover-viewport` will be scrollable. I implemented this behavior using progressive enhancement via `:has`. The [`:has` pseudo-class](https://caniuse.com/?search=%3Ahas) has cross-browser support. Ionic v7 supports some versions of browsers that do not have `:has` support. As a result, we fall back to the existing behavior in this environment. Developers are able to get this behavior on older browsers by explicitly setting `overflow: auto` on `.popover-viewport`. Fortunately, we will be dropping support for several of the older browsers versions in Ionic v8, so the need to do the manual opt-in should be less frequent as time goes on. ## Does this introduce a breaking change? - [ ] Yes - [x] No <!-- If this introduces a breaking change: 1. Describe the impact and migration path for existing applications below. 2. Update the BREAKING.md file with the breaking change. 3. Add "BREAKING CHANGE: [...]" to the commit description when merging. See https://github.com/ionic-team/ionic-framework/blob/main/.github/CONTRIBUTING.md#footer for more information. --> ## Other information <!-- Any other information that is important to this PR such as screenshots of how the component looks before and after the change. --> Dev build: `7.8.2-dev.11711383079.118d48a5` Testing: 1. Open https://codepen.io/liamdebeasi/pen/JjVJrZQ?editors=1100 (this has a dev build installed) 2. Click each button to open a popover. 3. Verify that each popover can be scrolled. I could not find a great way to automate this test, but let me know if anyone has ideas!
