Clicking on its icon does not give focus to a docked /tabbed Help browser
Reported by Stéphane MOTTELET (@mottelet)
BUG DESCRIPTION:
----------------
Clicking on the Help icon does not give focus to a docked Help browser and does not raise it when it is docked/tabbed (see similar bug 15626 for SciNotes)
Typing "help" in the command window does not work either.
HOW TO REPRODUCE THE BUG:
-------------------------
Dock the help browser e.g. in the console by forcing both windows to be tabbed
then click on the Help icon or type "help" in the console.
