hnakashima@ can you take a look?

This is a different codec then I thought, so probably unrelated to my JPX change. I haven't been able to reproduce locally either.
Status: WontFix (was: Assigned)
Cannot reproduce this locally (neither can clusterfuzz apparently). The only reason I can think of for a long execution time here is if the image was large, but the test case image is small (16x150).

Closing as not reproducible.
