Issue with tool selection on the tool bar
GIMP version: Fedora gimp-2.10.14
Operating System: Fedora 30 KDE X11
Description of the bug
Most of the time, I must click twice on a tool bar button to select a tool.
Concretely I encounter this issue when I am working : I click to select another tool and just after I realize the previous tool is still enabled. A second click on the tool button solves the issue. Issue is quite reproducible and very disturbing.
I suspect a GTK focus platform dependent bug ??? Else such bug would be fixed.
