Issue with minimizing comment chains after the recent update.

Hi everyone, not sure where to ask this but has anyone else had issues with minimizing comment chains in posts since the last update?

I will minimize a comment chain I have read through, and if I then upvote any other comment in the thread it expands every comment I had previously minimized. Doesn't do anything if I downvotes though. Has anyone else had a similar experience? It's kind of annoying. I like to minimize chains I have read through to make navigating the comments easier as I read through everything.

I use mobile only and have had the same issue on chrome and Firefox.
