Issue number: resolves #29763 --------- <!-- 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. --> If the nested content of an ion-item is conditionally rendered and goes from containing zero interactive elements to one or more, a render is not triggered in Angular and the item does not behave correctly for one or more nested inputs. ## What is the new behavior? <!-- Please describe the behavior or changes that are being added by this PR. --> - A mutation observer is created in `connectedCallback()` to watch for changes in item's child list. When the `childList` changes, two pieces of state that track whether the item needs to be interactive and whether there are multiple interactive elements are updated. - Add `disconnectedCallback()` and logic to disconnect Mutation Observer. - Create new function `totalNestedInputs()` with logic from existing `setMultipleInputs` function to be used for both `setMultipleInputs` and new function `setIsInteractive`. ## 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/docs/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. --> I opted for the MutationObserver over a `slotchange` listener because the `slotchange` fires synchronously on any slot within the shadowRoot, and the MutationObserver fires once on the item element itself. I attempted to add the minimum amount of logic to achieve this but there may be a more elegant solution that combines what `multipleInputs` and `isInteractive` are doing but requires more changes to existing code.
