Cannot click buttons under my messages (edit/copy)

Using the web version on Firefox, I am unable to click the buttons under my messages in chat (copy, edit), because they are there only when I hover the message - the moment my cursor leaves the field, to go click on the button, the buttons disappear. What I also found is that this particular one is a rather long chat, made as a branch from another chat, and the buttons actually all seem to work, until the first message after the branching - so, the first message under the “as a branch fom conversation” still has the buttons working, then there’s chatgpt reply, and all my messages (not the chatgpt replies, those are ok) after have the issue of the buttons hiding. Edit: I tried a few other chats and they also have the disappearing buttons under the branch notice, but sometimes even the first message under the branch notice is affected, and the last one not, the pattern isn’t clear to me. I can get to the button via keyboard and it does work when I press Enter. However, if I highlight the edit button by selecting it on keyboard (pressing Tab), it is still not clickable (nor is the “copy” one next to it).
