Comment (by sluicebox):

 I can reproduce this. I don't think this is a regression, but rather that
 there were still a few problematic coordinate/state/speed combos that the
 timing patch didn't cover. It usually works for me. These Grooper/Grycler
 bugs are awful!

 In the last year we've learned more about this global bug and have
 developed a treatment for its symptoms. This year I've fixed three other
 instances, two of them at the bottom of this same room, and all in the
 same way: #10747, #10760

 I just tried swapping the existing timing patch with a "normalize" patch
 and now I can't crash it. I like those odds!

 When I get a chance I'll make a PR so that you can test this too. I don't
 want to replace an existing patch until we're sure we've got this
 completely beat.

 I just saw that you were the original reporter two years ago, way to see
 this through! =)
