Is there source code fix or PR associated with this test. Since the PR
description mentions "MouseEntered/Exited" events does not occur properly.

Since TextArea and List are accessed only within invokeAndWait they need not be
volatile.

MouseAdapter can be used since only mouseEntered() & mouseExited() are being
overridden.

It is a bit odd to have a line break after sys.out. It looks better this way.
System.out.println("MouseEntered "
+ e.getSource().getClass().getName());

Same here. Line break.

Rows and columns can be specified for the TextArea to reduce scan time.
Suggestion:
textArea = new TextArea("TextArea", 10, 10);

After frame.dispose() assigning the var back to null is unnecessary.
