Hi all :)
I do extensive use of the "Special Windows settings" feature mostly to make usual apps remember its size and position, open at a specific place on the screen and so on. It's a feature that _I love_ and that makes a world of difference to me since it truly gives me the power to fully tailor my desktop experience.

This way i noticed when using Kontact -to which I set a fixed main window size- that when I launch it the sidebar will be shrunken to its minimum size and the only way to have it restored is to resize the window - as a workaround I do a quick twice Super+Space that I bond to the Maximize Window effect.

I supply a screenshot so you guys have a better idea of it.


Reproducible: Sometimes

Steps to Reproduce:
1. Launch Kontact and set the main window to a fixed N size - please note I'm referring to the "Special Window settings" and not the "Special Application Settings".
2. Close Kontact and launch it again.
3. If things go "right" you should have a shrunken sidebar.
Actual Results:  
I got a shrunken to its minimum sidebar that's impossible to drag and resize but that automatically restores itself once I start resizing the main window. 

Expected Results:  
The sidebar shows as intended.

Please check supplied screenshot.
