Editor crashes when renaming a file/folder by clicking outside of it

Issue description

The editor crashes when confirming a file/folder rename by clicking outside the selection.
This works fine in the Scene Tree dock.
I don't know why, but it's easier to reproduce in single window mode.

Steps to reproduce

1. Enable single window mode in the editor settings.
2. Select a file/folder in the FileSystem dock.
3. Press F2 or select the Rename option from the context menu.
4. Click an empty area in FileSystem dock to confirm the rename.
   Clicking outside the FileSystem dock shows a false warning instead.

I have the same error in single window mode, but it occurs quite randomly.
Most of the time renaming works fine, but sometimes it crashes if you click outside the selection.
