Sidebar cannot be disabled on mobile devices

[uneuen]

Steps to reproduce

1. Share internal link to a PDF file with a messenger (e.g. Signal)
2. Person who receives message clicks the link on their mobile device
3. Person wants to read PDF, but sidebar cannot be disabled (sidebar toggle button greyed out)

Expected behaviour

The sidebar should be disable by default.

Actual behaviour

The sidebar is enabled by default and the user cannot disable it. So basically, he cannot read the PDF because the sidebar is in the way.
