Scroll zoom broken on firefox: TouchEvent is not defined

Scroll zoom broken on firefox, this happens even if I force mouse mode on in preferences. I tried this on both Mac and WIndows same issue. Tried dumping cookies and private browsing same issue. Also when in mouse mode I see this error in the console:

 

Uncaught ReferenceError: TouchEvent is not defined

 

My guess is there is a bug and the touch event error is breaking the scroll zoom? Broken scroll zoom makes miro almost unusable.

 

I was away last week to login and not be able to zoom this morning, is this a known issue? How else can I report it if not? (On free plan)

 

Thank you
