Validate renaming by clicking outside the name

[raphj]

Is your feature request related to a problem? Please describe.

I saw somebody trying to rename a file by typing the new name and then clicking outside the input.
They expected the rename to be taken in account. This would be consistent with most file managers I know, including Dolphin (KDE), and most probably Mac's Finder too.

The actual result is that the rename is canceled. One needs to type Enter for the file to be actually renamed. This person actually thought Nextcloud was having an issue. They actually tried 3 times in a row.

Describe the solution you'd like

The rename should be taken in account when clicking outside the file input.

Describe alternatives you've considered

None

Additional context

Nextcloud.rename.mp4

dolphin.rename.mp4
