Renaming a file stops after first character if the window is just small enough for a scrollbar to appear

Bug description

If a Nemo window is just small enough for a scrollbar to appear, but not much smaller than that, and you try to rename a file, renaming stops after typing the first character.

Steps to reproduce

Set up a Nemo window that looks something like this, small enough for the scrollbar to show up but as big as possible other than that:

Select a file (it seems to work with any file) and press F2 to start renaming it.
Type a new filename with more than 1 character. It will stop renaming after the first character is typed.

Expected behavior

It should allow you to type in a full filename instead of just 1 character.

Additional information

If you press F2 after pressing alt-tab but before pressing any other keys, it exits the renaming immediately instead of letting you type a character.

This doesn't happen if the scrollbar doesn't appear, or if the window is resized small enough (I don't know the exact threshold).

Reproduce the issue in a Nemo window just large enough for a scrollbar to appear, then trace the F2 file-renaming path and its focus or resize handling. Confirm the fix by typing a filename longer than one character in the affected window sizes, including after Alt-Tab, without prematurely exiting rename mode.
