Expanding/collapsing a section causes other sections to teleport around

It appears the android browser doesn't like changing the transition randomly (what happens is the transform to reset the elements after the reflow doesn't actually occur until the page is touched again). If I don't turn transitions off, the reset still works, but it obviously looks terrible. Not sure why this is.

Also, the collapsed form fields seem to actually absorb clicks in some cases (they cover the form fields in the section below). They should probably be set to display: none when they're collapsed.
