Microsoft Windows [Version 10.0.19045.5247]
jdk-22.0.2+9

A DESCRIPTION OF THE PROBLEM :
Collapsing tree view causes rendering issues after previously changing size of tree view component. If you change the size of the component to higher the bug cannot be replicated anymore.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Run provided source code and press "Replicate the bug" button

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Row with name "two" is collapsed and right below it row "three" is visible and is expanded
ACTUAL -
Row with name "two" is collapsed and right below it row is expanded, but not visible, without label.
NOTE:
On macOS, another failure can be seen, as described in https://bugs.openjdk.org/browse/JDK-8347357

CUSTOMER SUBMITTED WORKAROUND :
Forked JavaFX branch with changes to javafx.scene.control.skin.VirtualFlow#layoutChildren - added resetIndex(pile) call to if(needsRebuildCells) block after resetIndex(cells)

FREQUENCY : always
