Tested using latest Nightly Version 58.0a1 2017-10-13 Build ID 20171012220111
Mozilla/5.0 (Macintosh; Intel Mac OS X 10.12; rv:58.0) Gecko/20100101 Firefox/58.0 and and reproduce the issue. 
Also I can confirm that this is a regression (works just fine using Nightly 58.0a1 (2017-10-06) (64-bit) build). 
Similar issue 1406785 (also a regression around that date) - which may be related with this bug.
gabe.saravia Thank you for reporting it.

There's no CSS in this test.

Would you please run mozgression tool to help get the regression window, Deac Alin?

Yes, you are right, at the moment it seemed the right component(my bad).

Thanks Deac! I see so errors on the latest nightly. As bug 1405571 was backed out, could you verify if it's fixed already?
