It’s complicated. I first used the chain link which is purely internal. This expands the msg and offers the “show context” option which gives nothing (due to the bug). Then I try the fedi icon and nothing happens at all… no expansion or anything. But I can see that the button is sensitive because it flashed as I clicked it. So then I forcefully copied that external link into a new tab in Tor Browser and it just shoots a blank. No text at all. Then I copied that same Lemmy World link into ungoogled chromium running over tor, which shows #LemmyWorld’s blockade I screencapped.
Note that ungoogled chromium has experimental value and reveals the problem (Cloudflare), but all versions of #Lemmy I have encountered have always been wholly broken in ungoogled chromium. Lemmy forces the use of Firefox-based browsers (and last time i checked Lemmy is quite useless in text browsers as well).
