After installation is done moving cursor over optional packages makes the views relayout by jumping about 5(?) pixels up.

The problem is only reproducible when status message doesn't fit into current view which happens when translation is too long which happens with in Russian locale with a ling "VBOX HARDDISK" string here ​https://git.haiku-os.org/haiku/tree/src/apps/installer/InstallerWindow.cpp#n498

As a test case one can make Choose the disk you want to install string longer for it not to fit into the view. If you make it long enough Set up partitions and Begin buttons will either be cut off or disappear completely.

The easiest solution is to make the window wider to make sure the longest string fits on 4 lines. You can experiment with changing the "22" here: ​https://git.haiku-os.org/haiku/tree/src/apps/installer/InstallerWindow.cpp#n182 (the width of the text view is currently neough to show 22 "W" characters).

Let me know how wide it needs to be. We can also make it higher (currently it is the same height as the logo) if needed.
