Bug: Resizing LazyVerticalGrid crashes in combination with item span > 1

[JuBan1]

Platform: Linux Desktop JVM Compose Version: 1.2.0-alpha01-dev755

I'm using a LazyVerticalGrid that has full-width items. Upon resizing the window (and therefore the Grid) I can reliably produce a crash within a few seconds of trying.

Steps to reproduce:

• Use the code below.
• Start the application
• Resize the window by dragging it around. (See attached video.)

Notes:

I have played around with it a little, and identified a few things about this crash:

• It only happens when items with a non-default span are used. If I remove the header items or set their span={GridItemSpan1)} the crash stops happening.
• It seems it is important that there are enough items to fill the whole viewport.
• It's important to use GridCells.Adaptive. The crash won't usually happen using GridCells.Fixed(num). However, I can produce the crash by using Fixed(num) and varying the num, for example via BoxWithContraints { num = maxWidth/200.dp; ... }.
