I made a post to [email protected], then in another tab I subscribed to [email protected]. Back in the tab I made the post in, the page updated itself to look like I made the post in [email protected] instead. I didn’t refresh the page or do anything else… It just changed by itself.
I’m doing further testing and it keeps happening. I keep my post open in a tab and subscribe to communities in another tab and each time I do the tab with my post updates to whatever community I just subbed to.
If it matters: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:109.0) Gecko/20100101 Firefox/114.0
More testing: Seems to happen when I sub to communities on other instances, not my home server Lemmy.world.
