Refreshing an open connection loses scroll bars / ability to scroll

[exninja]

Describe the bug
While having an open connection where the files and folders exceed the window size, the vertical scroll bars display - this is good.
Clicking the refresh button may lose the scroll bars and ability to scroll as if CD is unaware there are more files/folders beyond the view window.

To Reproduce
This isn't guaranteed as the behavior is inconsistent.

1. navigate to a site.
2. expand a folder that contains many files - notice the scrollbar is on the right.
3. click "Refresh" button in top tool bar - the scroll bar might disappear
4. try refreshing a couple more times if the scrollbar does not disappear the first time.

Workaround
No need to disconnect to get the scrollbar back - just resize the window.
