Contracts info are merged in R&D panels
Hello there!
I just stumbled upon a bug with the contract window. It seems that part of the window for contracts is showing into the R&D parts icons when it shouldn't. I join here a screenshot of the problem

To reproduce this:
- Have a window opened in the building selection screen (have it on the right of the screen I guess?)
- Open R&D centre and chose a research node.
Not sure if this is a problem of z-value or what, maybe it's just the R&D centre who's doing something it should not. I suppose it could be fixed by forcing the window to close whenever one open the R&D centre? The problem seems to be non existent when that's the case.
Something similar happens in some cases if it is positioned over the parts list in the editor.
I can fix the R&D problem by just turning the UI off whenever a Space Center building is opened, which is something I should have been doing anyway.
