Right, here's a
very rough work-around before an actual fix can be found:
1) Hit F12 to open the 'developer tools' panel
2) Go to the 'Emulation' tab
3) Switch the 'Document mode' from the default (7) to 10 (Edge probably works too)
Issues:
- Only affects the currently open tab
- You need to keep the developer tools panel open (you can scale it down, though)
- May or may not affect the functionality of other features on the site
