Regression range

  • unknown

:danibodea, if you think that's a regression, could you try to find a regression range using for example mozregression?

QA Whiteboard: [qa-regression-triage]

This issue reproduces in builds as old as V70.0a1 so it is safe to assume that this is not a regression, but an issue since its implementation. Further back investigation could not be possible because builds around v60.0a1 would instantly crash when loading any content.
