This page load shows a 429 on the Special:EntityData call from the wikibase UI itself
This results in none of the statement editing functionality loading on the page, and it doesn't really tell the user at all that this is what is happening
For me, this resulted in me refreshing the page a bunch of times (more requests) to try and get it to work (eventually getting a 200) for the Special:EntityData call, and allowing the editing tools to load
I imagine that the wikibase UI itself could better handling for 429s for this call to special:EntityData
I also imagine that the rate limiting might be able to have better behavior for some referrers, or in the case valid cookies are present etc?
However, I'll leave this ticket as is for now...
