BUG: TableView's setMouseTransparent method does not make mouse transparent

[Ty Young]

Bug review ID: 9057302.

TavleView's setMouseTransparent no longer makes mouse events(like 
clicking) transparent for that TableView when set to true in JavaFX 11. 
In Oracle 9 and 10 it did, however. I vaguely remember compiling OpenJDK 
10 with JavaFX integrated and had the same issue even though Oracle 10 
did not have the bug.


I personally use this to create an On Screen Display for displaying some 
GPU information while playing games in Linux(Yes, I know it's incredibly 
bad to do that since the desktop is still being rendered). Because of 
this bug, in-game menus cannot be clicked if they are in the top left 
corner(where the window is) as the mouse transparent method is no longer 
working.


(While i'm at it, does JavaFX *always* render the desktop even if a 
JavaFX application is fullscreen?)
