Steps to reproduce:
1. Plug in camera/mp3/phone.
2. Launch Nautilus, open ~.
3. Press F3, you'll see two panels of equal widths.
4. Open camera/mp3/phone folder by clicking on it leftward.

Status changed to 'Confirmed' because the bug affects multiple users.

The same thing repeats when opening a trash by "Trash" shortcut. After manual panel size correction and switching on other shortcuts and switching "Trash" again, Nautilus doesn't change size of panel.

The split mode has been removed which deprecates this issue
