       Reviewed-by: Jonathan. — Pavel Safrata / detail

JPA profiles show that the time spent in Scene.doLayoutPass() was increased from
0.173 sec to 26.690 sec (total run time was 30 sec). This is because we now spend
19.434 sec in com.sun.javafx.scene.control.skin.ScrollPaneSkin.layoutChildren() and
 7.215 sec in com.sun.javafx.scene.control.skin.TextAreaSkin.layoutChildren().

So, looks like the regression is caused by "RT-34219: fixed TextArea's scrollbar after deleting its content."

Note, the regression is observed on all platforms including Windows and MacOS.
On Windows the regression is better noticed in SW pipeline.
