The original PDF.

To confirm this only affects beta? I wasn't able to reproduce with Firefox 93.

Hi, Brendan! I could only reproduce this once and didn't stubble upon it for too long considering the priority of other work.
I assumed it was some specific data I introduced in the PDF before saving it with Beta92.
I hoped you could determine what the specific information is by using the attachment in comment 4.

I'll do my best to determine the cause tomorrow.

I can confirm it also reproduces on Nightly. I've opened the affected and original PDFs in Nightly and copy-pasted all information and saved it from nightly. It is still reproduced. Furthermore, I tried tracking the exact field that caused it by saving a few different PDFs with parts of the affected one's information, but it seems like it is not connected to a specific character introduced or field completed, but to a group of them...

I've erased as many fields to attempt to narrow down the least data in it before it stops reproducing and this is the last saved PDF I got. I really hope that the Adobe errors say something useful about the issue because I've hit a wall.

We need to decide whether this should block XFA, given that it is already affecting AcroForm too.
