[e10s] <select> drop-down doesn't appear near <select> if CSS 'transform' is applied to iframe
I have a problem with Firefox Beta 52. It also happens in Beta 53, Nightly 55. Doesn't happen in ESR 45. (Well, I remember that it happened in some other cases, but in this exact case there's no bug in ESR 45. I'm not sure whether this is considered as regression) Sometimes drop-down list of <select> options appears far away from <select> if CSS 'transform' is applied. Here's how to reproduce it: 1. Open attached document 2. Click on <select> Result: drop-down appears in a distance Expected: drop-down list should be exactly below the <select> I've added "[e10s]" in the summary, because it isn't reproducible if in Nightlly I disable multiprocess. Please correct me if this logic is incorrect.

NG on Windows and GNU/Linux build but works on macOS. Nothing shows up on Edge and Chrome when loading test case in this bug.
