…s in child routes (#30839) Issue number: resolves #30700 --------- ## What is the current behavior? When a sheet modal with showBackdrop=false is rendered in a child route (nested ion-router-outlet), the parent content becomes non-interactive. Clicks on buttons or other interactive elements in the parent component are blocked, even though showBackdrop=false should allow background interaction. Two separate issues contributed to this bug: 1. **Root locking with `backdropBreakpoint`**: The `shouldLockRoot` logic in `overlays.ts` didn't account for `backdropBreakpoint`. Modals with `backdropBreakpoint > 0` were still locking the root with `aria-hidden`, even though developers expect background interaction when the modal is below the backdrop breakpoint. 2. **Child route wrapper blocking**: When a modal is in a child route, the child route's page wrapper (`ion-page`) and its parent `ion-router-outlet` remain in the DOM with `position: absolute` covering the viewport. Even after the modal is moved to `ion-app` and has `pointer-events: none`, these wrapper elements block clicks to the parent page's content. This issue stems from [#30563](#30563), which added root-locking behavior that didn't account for modals that allow background interaction. A partial fix in [#30689](#30689) partially addressed `showBackdrop=false` and `focusTrap=false`, but missed `backdropBreakpoint`. ## What is the new behavior? Sheet modals with showBackdrop=false or focusTrap=false now correctly allow interaction with parent content when the modal is in a child route. Improvements: - Recalculates isSheetModal in present() to handle Angular binding timing - Sets pointer-events: none on the modal element and its original parent elements when background interaction should be allowed - Cleans up pointer-events on dismiss - Adds regression tests ## Does this introduce a breaking change? - [ ] Yes - [X] No ## 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: ``` 8.7.12-dev.11765060985.14ad27fb ```
#30845) Issue number: resolves internal --------- ## What is the current behavior? When using ModalController to present a modal in Angular applications, the browser becomes non-responsive and hangs in some circumstances. This regression was introduced in #30544 with the addition of a MutationObserver that watches document.body with subtree: true to detect when a modal's parent element is removed from the DOM. For controller-based modals, this observer fires on every DOM mutation in the document, causing severe performance issues during Angular's change detection cycles. ## What is the new behavior? The MutationObserver for parent removal detection is now skipped for controller-based modals and when the cached parent is the app root (document.body or ion-app). These parents are never removed from the DOM, so observing them is unnecessary. This prevents the performance issues while still maintaining the parent removal detection behavior for inline modals with meaningful parent elements. ## 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. --> Current dev build: ``` 8.7.12-dev.11765231260.1def96ab ``` --------- Co-authored-by: Maria Hutt <[email protected]>
