Apologies for churn on browser tests - locally I get this weird error which I haven't been able to debug yet so scrambling in the dark a bit

Might be useful to try setting DEBUG=*, you'll get a lot of output but you might find some hints before the crash

[anuraaga]

Thanks @Flarna for the review!

[obecny]

I see you have some error on browsers tests, can you please check if it works fine on karma v.4 instead of 5 ?

[obecny]

Is this working for you as karma 5 doesn't work for me (osx), had to downgrade back to 4

[anuraaga]

@obecny Thanks - with karma 4 I get less error output, just 19 04 2021 11:13:24.930:ERROR [karma-server]: UnhandledRejection. As the CI is ok with karma 5 and I couldn't find an improvement with 4 leaning towards leaving it as is for consistency with the other projects.

@dyladan would be awesome if this could be merged with its approvals :)
