It seems that earlier this day, the mediawiki-extensions-qunit-jessie job has started failing with errors like this (example console):

CCing @WMDE-leszek because he’s been working on the browser tests and I don’t have much else to go on.
Repeating the CI build sometimes makes the error disappear (e. g. on https://gerrit.wikimedia.org/r/c/416765/, patch set 6, after the second recheck).
