Hi @aryx Could anyone check if this is related to bug 2009206? Thanks

Comment 2

[Sebastian Hengst [:aryx] (needinfo me if it's about an intermittent or backout)]

Similar to bug 2017267, this is a regression from the changes in bug 1922974.

• line 61 of the test is mentioned
• Close to it, the image/jxl format is referenced.
