Edit: Apparently, you cannot write direct html entities.

Edit: And you cannot directly write the characters either. Rendering seems rather finicky on Firefox, while Chrome seems somewhat consistent.

Actually, on Chrome, copying the characters directly "kind of" worked. They're still shown next to each other, yet some of them combined and actually created towers.

Writing the HTML entities on a private webpage and then copying them over seemed to work the best.

Edit: Apparently, at least some of the Devanagari unicode behaves similarly.

Edit: Several other languages combining marks taken from https://www.cogsci.ed.ac.uk/~richard/unicode-sample-3-2.html and https://www.compart.com/en/unicode/category/Mn seem to also work.

After further testing, Both browsers are really finicky, and have wildly different interpretations of pasting combining characters directly, vs writing HTML entities, vs copying the combined stack from an existing site.
