the issue is reproducible on skia as well the VirtualizingPanelLayout::MeasureOverride get spammed for 250+ times for a simple LV with 5 items
it is worth noting that it only starts getting spammed when we mouse-over the LV area if the cursor was already over the LV area, before/while the LV loads, then this issue wont occur even if you mouse-exit and mouse-"re"enter again which could indicate the problem is pointer and/or visual-state related
the amount of calls doesnt seem to scale with the complexity of the ItemTemplate used
Is there a repro for this? I've tried and it doesn't seem to reproduce on my end (tried skia).
Current behavior
When running the sample
ListView_Expandable_Item
, on android, checking one of theCheckBox
causes theListView
to be re-measured multiple times, driving all items to be detached and re-attached from their parent up to 23 times ...Expected behavior
Size caching / limited scope invalidation should prevent any re-measure/layouting of the
ListView
itself.How to reproduce it (as minimally and precisely as possible)
