A DESCRIPTION OF THE PROBLEM :
Under very rare conditions the contents of a TableView shrinks to only one row. This seems to happen when the vertical scrollbar just appears but shows no effect when trying to scroll. So the content still fits completely.

After clicking to some rows all rows disappears until only one is left. We made some screenshots and created a screen cast video.

We were able to reproduce the problem under macOS and Windows. Older versions of JavaFX did work

JavaFX 17.0.2 - no bug
JavaFX 17.0.6 - bug
JavaFX 17.0.8 - bug
JavaFX 18.0.2 - no bug
JavaFX 19.0.2.1 - bug
JavaFX 20.0.2 - bug
JavaFX 21.0.1 - bug
JavaFX 22-ea+16 - bug

Seems that the problem was introduced with some fixing for TableView problems and backported to JavaFX 17.

REGRESSION : Last worked in version 16

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Start the demo application and resize the height of the window until the vertical scrollbar appears. Use the scroll wheel or move the scrollbar. The content should not show any visual changes.

Click into the last and into the first cell afterwards until the effect appears.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The rows should not disappear.
ACTUAL -
Only one row is left in TableView.

CUSTOMER SUBMITTED WORKAROUND :
Only solution we found was downgrade to JavaFX 17.0.2.
