To reproduce:
apply analyzer3.css file from attachment to the root container
add a button to the root container
add AnchorPane
apply analyzer1.css file from attachment to the newly added AnchorPane
open Analyzer
scroll to the -fx-text-fill property
place mouse pointer over fx-text-fill value in Stylesheet column -- only one gearbox is displayed -- BUG
click on it, check that it works fine
move mouse pointer to the place where second(one for the winning rule) gearbox should be drawn press on it -- opened popup is incorrect, it contains right menu item for opening analyzer1.css and incorrect menu item for "reveal in explorer\finder" for analyzer3.css -- BUG
