What specific section or headline is this issue about?

html-only_dialog

What information was incorrect, unhelpful, or incomplete?

The embedded HTML-only dialog example seems broken. Clicking the Ok button does nothing, on either Firefox or Chromium.

Following the Play link through and interacting on the playground behaves as expected.

I am not quite sure what could be causing this issue. I've poked around in the developer console a little bit, but didn't notice anything out of the ordinary.

What did you expect to see?

Do you have any supporting links, references, or citations?

No response

Do you have anything more you want to share?

I am using uBlock Origin. Disabling it did not affect the issue, however.
