List of steps to reproduce (step by step, including full links if applicable):

• Start to edit any page in the Mobile Editor
• Try to access that page's talk or history, related changes, log pages or even your own notifications.

What happens?:

• You can't because everything is hidden behind a toolbar with nothing in it (see T106266 for an obvious thing that should be in there)
• You can't go back because then you lose your edit - this is very inconvenient if you didn't open the editor in a new tab
• Your best bet is copy-pasting the URL, opening a new tab and then editing the URL (or you can guess that the close button will even though back doesn't)

What should have happened instead?:

• You can still access links that allow you to open them in a new tab for reference while making your edit.
