Firefox: Image upload is back to being stuck after hitting 100%

[askfongjojo]

In the latest rack2 build, I was unable to import images on Firefox. It stopped progressing after hitting 100% bulk-write completion:

I saw this error on the browser console which may be unrelated:

I'm retrying the upload (for the third time) and watching the network tab. Will add more information if it reveals something useful.

Yes, I think the console error is unrelated.

The Omicron issue is still open oxidecomputer/omicron#3559 and there’s a related Dropshot issue oxidecomputer/dropshot#726 that it looks like we’re ready to move forward on. The Dropshot thing might be good for me to take a look at because I’m low on urgent tasks.

The presentation we always saw in the network tab was that one or more of the chunk POSTs would just hang forever with no info available when you click on it.

The upload succeeded on the 3rd try (though it ended with an unrelated error with disk deletion). Since I didn't encounter this issue in the last two weeks, I thought I should log this just in case it's caused by some other changes. I'm closing this as a duplicate of the open issues mentioned above.
