Mobile diff drawer contents should be flush with the page container
Developer notes
This is not anything to do with icon changes we made but the post-content element we use.
We'll want to reset the left/right margin on mobile, without breaking it for the other breakpoints. A @media query using max-width that applies up to tablet should suffice here.
@media all and ( max-width: @width-breakpoint-tablet ) { #mw-mf-userinfo .post-content { margin: 0; }

Hamburger, WIkipedia logo and user icon should align in all cases.
