Merge branch 'ios-tooltips' into 'master'

Set webkit-overflow-scrolling to auto for children of body.

## What does this MR do?

Fixes weird tooltip layering behavior in iOS Safari. See screenshots and/or the original issue: https://gitlab.com/gitlab-org/gitlab-ce/issues/22816

## Why was this MR needed?

Tooltips were cutoff in Safari.

## Screenshots (if relevant)

Also, as part of this fix, I removed applications of `-webkit-overflow-scrolling: auto` in two other places where they're no longer needed. One was the file-holder. I made sure I could reproduce the behavior this was intended to fix, and then made sure this MR still fixed it. 

Here's the errant behavior:

Here's what it looks like with this MR:
