Sample app which shows the problem described
If ListView context action "Text" or "IsDestructive" property is bound to the item props, several updating of those properties freezes an iOS app. To see:
1. Start the sample attached on iOS device or simulator (any iOS version);
2. Click several times on some item. After 15-20 clicks the app will be frozen.
Depending on items count and complexity, the freezing may be occurred on 3-5th bound property change.
Reproducible on 2.3.2, 2.3.3 and 2.3.4.
I was able to reproduce the issue described with the attached project. In the project, each press of the cell fires off a property changed notification for the MenuItems and after ~20 presses the app started to run and respond to the event very slowly, though I never saw it completely freeze or crash. I ran the project on a 10.3 simulator and 10.2 device.
On Android, there was no degradation in performance so this seems to only be happening on iOS. I can confirming this report so the team can look more into this.
