RFR: 8320057: [macos14] javax/swing/JToolTip/4846413/bug4846413.java: Tooltip has not been found!

[Prasanta Sadhukhan]

Test failing on macos14 citing "ToolTip not found"...Investigation shows that the mouse is not moved when invoked 1st time to desired location on screen causing tooltip to not show...However, subsequent runs of the same test without any change causes it to pass every time.
Workaround is proposed to check if running on 14.x, then invoke a dummy mouse movement to same location which causes the test to pass for several iterations in macos14 environment.
