[Expander] should take screen width into account
|Reported by:||diver||Owned by:||stpere|
After clicking "Show contents" Expander will resize itself to fit the results (see #3797). But currently Expander doesn't check screen width, so if archive contains many subfolders or files with long filenames Expander will resize itself out of screen. Try attached zip file to see it.
Tested with hrev35129.
