Scrolling down in some view inspectors causes a crash #719
Description
Environment
- Platform+version: iOS 18.5 (22F76)
- FLEXing version : NSExceptional/FLEXing@04433a9 (latest)
- FLEX version: 2bfba67
Bug Report
When clicking on certain elements in the view hierarchy explorer, scrolling down after the inspector view has loaded will crash the app. Not many views have caused this behaviour for me, but the ones that have do it reproduceably in the exact same way each time.
Additionally, the crash is not caused until you start scrolling (potentially loading in problematic table cells?). Using the quick navigation bar thing on the right, i can get to the bottom of the inspector just fine. And I can scroll all the way back up, right until it hits the top of the ivars section.
