taskmanager: Fix sometimes not showing labels in tooltip
Review Request #126162 - Created Nov. 24, 2015 and submitted
This is basically patch by Fabian Vogt from the bugreport.
But it is still not fixed, so I opened the RR myself.
Bug is now fixed, I cannot see any side-effects.
Reliable way to reproduce bug:
- Set some launcher to always show
- Make sure the app from step 1. is not running (so you have the launcher in taskmanager without running app)
- Mouse over the launcher from step 1., let the tooltip show and then move mouse out to hide it.
- Mouse over some other taskmanager entry that is for running application
- Tooltip is shown without labels
