IconView fails to refresh after reversing a cut/paste operation

[jeremypw]

What Happened?

Cut/pasted a file between two folders in separate tabs. The file appeared in the second folder OK. The cut/pasted the file back in to the first tab. The view blanked and did not refresh until the view was resized or the refresh button was pressed. The file was successfully moved. No terminal warnings were given. Only happens with IconView. Moreover, it only happens between two tabs in the same window. If the second tab is in a separate window then the view redraws correctly.

Maybe related to some other issues involving refreshing but this is the easiest to reproduce

Steps to Reproduce

Using IconView:

1. Create a folder and within it a child folder and open them in separate tabs A & B
2. Create a file in A
3. Cut/paste the file from A to B
4. Cut/paste the file from B to A
5. Notice tab A appears blank until refreshed

Expected Behavior

The view always updates when a file is pasted into it.

Curiously this seems only to happen if one folder is a child of the other and both of them are in IconView 🤷

Happens even if the file pasted back is different from the one previously cut.

Can also be triggered using Undo and Redo shortcuts in which case it possible for the folder losing a file to become blank.

A refresh of a "blank" folder also occurs when <Alt><Tab> is used to switch another app and back, or simply focusing another window.

I suspect this issue is to do with something upstream so may not be easily fixable in Files. It is not fixed by inserting queue_draw () command to try to force the IconView to redraw. For some reason the window manager is not picking up that the IconView window needs to be redrawn (although it gets as far as clearing it)
