drag and drop of files should not "hang" on file upload progress bar

[sbarbosadataverse]

Tried uploading 30 image files to a dataset and several times the upload status bar just hangs and forces me to restart the upload. It never resolves

This reminds me a bit of #4511 and the "more feedback about errors" feature @qqmyers added in pull request #4522

[qqmyers]

Could be ... what version is running? The code to check errors was in that original PR, but it was broken with provenance additions and only works again after #5466.

[pdurbin]

@qqmyers good point. I'm sure @sbarbosadataverse is using Harvard Dataverse which would be Dataverse 4.10.1 and that fix in pull request #5466 will ship in the next release.

I just uploaded 30 image files averaging about 1MB each and haven't seen a stall, yet. Maybe this issue's been improved since last February?

[pdurbin]

@jggautier since you also just opened #6481 (thanks), I assume your observation was on Dataverse 4.18.1

[jggautier]

@pdurbin is sure was!
