Logged-out view is wider than screen, left edge cut off, can’t be scrolled

[daprice]

Steps to reproduce the problem

1. Visit a mastodon server while logged out.

Expected behaviour

Landing page layout should be responsive and not go off the screen horizontally

Actual behaviour

Landing page layout appears to be a fixed width wider than the screen, but can’t be scrolled horizontally. This appears to affect all logged out views including viewing a post, etc.

Detailed description

This is what I see when I visit mastodon.social in Safari on an 11” iPad Pro. The left side of the page is off the edge of the screen and I can’t scroll it into view. Even if I manually zoom in/out, that part remains cut off as if there’s negative padding/margin on those elements. The right side of the page also appears to have less padding than it should.

Technical details

Also affects desktop Safari if the window is narrower than the width of the page content. Can also reproduce in Firefox.
