Defect Fixes
Fixes #16246
Commit e7b611 introduced a regression in the size calculation for
TreeTable
component with a"flex"
height configuration. The issue arises because the spacer size is no longer being updated correctly. As a result, the scrollbar resizes itself during scrolling, which causes jumping of the scrollbar.I have replaced the window-size listener with a
ResizeObserver
, because the number of visible items in aTreeTable
with virtual scrolling must get recalculated if the view size changes. The new observer should handle window size changes, important to theTreeTable
, equally well.
