 In #34931, embeds were added to static frontpages, and there was a
 discussion of how this would affect an existing page with a slug of
 /embed/.

 The solution was:

 - an existing page with slug /embed/ will work as is and disable the
 pretty embed URL
 - new pages can't be created with a slug of /embed/.

 However, this did not work properly. On a site of mine, there is a page
 with URL /embed/ that was working fine prior to this upgrade. Now:

 - if you visit /embed/, you are redirected to the homepage.
 - if you attempt to edit the page, the slug previews as /embed-2/, meaning
 editing the page content and saving has the unwanted side effect of
 forcing the URL to change and all links to the page to break without
 warning.

 Suggested changes:

 - fix whatever is incorrectly redirecting the URL
 - allow a slug of /embed/ to continue to save as-is if it already exists.
