[Bug]: all new sandboxes (with ShowRenderedHTML) break

[tdd]

Summary

Pretty much all new sandboxes break in last week's work. Noticed this on yesterday's weekly translation sync.

Every single sandbox with this component breaks. I included just one example page.

I think this was broken in #6496
