Several years ago, when I worked at FB, I ran into a similar bug on an early internal version of a Messenger rewrite. Sent pictures to one chat, showed up in another.
My bug report on it kicked off an absolute maelstrom of dev activity and investigation. High level engineers showed up in the comments. Lots of immediate followup. The severity was clearly understood and resolving it was clearly prioritized.
I exclusively use Signal now, but the discrepancy between what I see here and what I saw there is pretty disheartening. This kind of bug is not only a massive privacy risk, but it also massively erodes user confidence and trust.
