Sheet destination with background interaction is not dismissed when parent is dismissed on iOS 26 #3783
Description
Description
Given the feature structure:
Parent > Child > Sheet
When the child feature has a sheet destination that is presented with sheet(item:content) and uses presentationBackgroundInteraction, by dismissing the child (not the sheet) directly, the sheet is not correctly dismissed. It will remain presented over top of the parent feature, after the child has been dismissed.
Appears to have been introduced in 1.21.0 by #3729
This worked normally (although with visual glitches also present in vanilla SwiftUI) pre-iOS 26. Continues to work in vanilla SwiftUI in iOS 26
Checklist
- I have determined whether this bug is also reproducible in a vanilla SwiftUI project.
- If possible, I've reproduced the issue using the
mainbranch of this package. - This issue hasn't been addressed in an existing GitHub issue or discussion.
Expected behavior
Dismissing a feature should dismiss all of its children.
Actual behavior
The presented sheet remains active, though actions are cancelled and purple warnings are reported
