Maybe. I haven't had it happen yet personally, but I think it's a matter of time.
As I get more used to the interface I perform the actions I am used to more quickly and eventually blindly.
I think I only haven't run into it because I don't usually scroll a set distance down to the comments.
I expect that as soon as I find a series of say a few tens of posts with similar layout I only want the comments from, I'd run right into it, ruining my scroll position in the feeds list instead.
I have definitely had the sidebar bug happen often enough I recognized it in ops report without op themselved knowing why it happened.
Something I don't think would happen to me but could happen to others, is that if you tap a different post while one is already opening, or tap a sub, the app breaks badly.
I think the proper thing would be to at minimum stop all interactions with the posts pane once a post is opening. Canceling ongoing swipes and making it fully non-interactive would ofc be better.
Btw., does the post open animation respect the system animation speed? That'd also help in my case, making it 3-5x faster.
