It’s set to fade in from 0 opacity, for some sort of unnecessary “ooh look it’s fancy” effect. My guess is that if you check the console you’ll find that it hit some exception before it completed its little fade-in effect.
It seems to be caused by the FediAct addon, which doesn’t make any sense. Disabling the addon fixes the page without needing a reload, so it must be a CSS issue rather than an exception.
Might be worth reaching out to the addon authors. Hard to say whether the page or the addon is at fault, but they might be interested to know it even if it’s the page’s fault.
