--- Comment #2 from Alex Christensen <achristensen at apple.com> ---
This changed with https://trac.webkit.org/changeset/266399/webkit which adopts the behavior of the URL specification at https://url.spec.whatwg.org/#fragment-state
The percent encoding starts after the '#' character, which begins the fragment of the URL.  Your example also percent encodes those spaces in Firefox.

I've noticed some odd things about fragment encoding in different browsers:
Browser     | new URL("data://example.com/# <>") | new URL("data://example.com/# <>")
-------------------------------------------------------------------------------------
Firefox 88  | data://example.com/#%20<>          | http://example.com/#%20%3C%3E
Chrome 90   | data://example.com/# <>            | http://example.com/#%20%3C%3E
Safari 14.1 | data://example.com/#%20%3C%3E      | http://example.com/#%20%3C%3E

I've raised https://github.com/whatwg/url/issues/597 and intend to implement my proposed change to increase compatibility, which would revert https://trac.webkit.org/changeset/266399/webkit for non-special schemes.
