[BottomSheetBehavior] ArrayIndexOutOfBoundsException onLayoutChild()

https://github.com/material-components/material-components-android/blob/64b066a0c46e78f2c41403dd566fbc1ce8125b66/lib/java/com/google/android/material/bottomsheet/BottomSheetBehavior.java#L612C1-L612C1

I'm getting the following stack trace in production builds, coming out to around 300-400 instances per month.

Fatal Exception: java.lang.ArrayIndexOutOfBoundsException: length=15; index=15

It looks like there might be a race condition where the size of the callbacks array is reduced while iterating through the list.

Start at BottomSheetBehavior.java near the referenced line and the onLayoutChild() stack frame, then inspect how the callbacks list is iterated and changed. Reproduce or add coverage for the reported length=15, index=15 failure, and verify that callback updates no longer cause an ArrayIndexOutOfBoundsException.
