Regression, FileBrowser copying a file via Ctrl+C and Ctrl+V does enter renaming mode unintentionally

This definitely regressed during 0.4.15-dev-xxxx.

Reproduction steps

• open explorer file browser and select a file
• press ctrl+c with the intention to copy it
• enter some other folder and press ctrl+v to paste it

Observed result
the file is pasted as expected, but it erroneously enters the renaming mode then.
