#162954 (comment)

Going to disable the job for now, not sure what's going on. Can re-enable when we figure out what is causing the failure.

We re-enabled it in #162573, and Merge CI passed there. But seemingly now fails in the rollup.

FYI @erickt

Nevermind I didn't notice the rollup has #162423, sorry.
