Regression-Range:
This is a very recent regression, could not reproduce it on yesterday's Nightly build. Will look into it asap.

Severity-Suggestion:
S3 severity although I am not aware of the impact or meaning of this error so leaving it to engineering to measure that.

Bugbug thinks this bug should belong to this component, but please revert this change in case of error.

Component: General → Console
Has Regression Range: --- → yes

Thanks for the regression range Alice!

Hey Alexandre, please take a look at this when you have the time, thanks.
