Support Forum: Embed loses fragment identifier

[joyously]

I put this URL into a forum reply, and the embed didn't have the fragment identifier.
​https://wordpress.org/support/article/writing-posts/#visual-versus-text-editor

The link in the embed was to the page without the fragment ID, thus losing the specific detail that was wanted.

Could be related to #3916

Confirmed

I added https://wordpress.org/support/article/writing-posts/#visual-versus-text-editor to https://wordpress.org/support/topic/test-helphub-urls/ (now archived). When editing that post the link is correct, though viewing the post embed the link is truncated to https://wordpress.org/support/article/writing-posts/

This ultimately comes back to a short-coming of the WordPress oEmbeds, bluntly fragments are not supported.

If you look at the resulting embed, it's something like this:
https://wordpress.org/support/article/writing-posts/embed/#?secret=...

I think there's two things in play here:
1) Core doesn't support Fragments, and should not embed URLs if they have fragments, and/or should support fragments (This needs to be filed on core.trac)
2) The Support Forum can probably work-around this and disable embeds for URLs which have a fragment specified.
