So this is our fault.

When trying attachment 8735300 [details] with Firefox 52.0a1 buildID=20161017030209:

- an horizontal scrollbar is rendered
- "abcd" text is accessible
- "abcd" text is not visible at initial page load: you must use the horizontal scrollbar to see it
- the horizontal scrollbar thumb is not draggable (we have encountered and reported this symptom in other bug reports)

Yep, There is small progression. scrollbar is displayed on 51.0a2+, but not on beta50.
Mass bug change to replace various 'parity' whiteboard flags with the new canonical keywords. (See bug 1443764 comment 13.)
Keywords: parity-chrome, parity-edge
Whiteboard: [parity-Chrome][parity-Edge]
