Android crashes on Modal Animation when backgrounded

[rs-lkroneman]

Description

While an animation is in progress and the app is backgrounded the app crashes with an java.lang.IllegalStateException: Can not perform this action after onSaveInstanceState

This is currently our number 1 exception in production.

All of our stack traces point to the ModalContainer.Destroy() method

We looked at the following issues to see if they were related or had any workarounds, they seem like similar issues but didn't seem like the same to us.

• App crash when is started from another app. #19374
• Crash when changing mainpage #17769
• Java.Lang.IllegalStateException after MainPage swap #11501
• Java.Lang.IllegalStateException: Can not perform this action after onSaveInstanceState #11259

Further we believe that updating the line to use CommitAllowingStateLossEx instead of Commit would fix the issue, however we're unaware of the implications of that change.
