Comment (by needle):

 Not quite sure how best to describe this, but [47937] breaks rewrite rules
 that use a Page as the "top level" of a "virtual hierarchy", where the
 path that follows the top level slug is interpreted as configuring the
 Page.

 So, for example, the URL `https://my.domain/mypage/one/two/` can be
 rewritten via `add_rewrite_rule()` to render `https://my.domain/mypage/`
 with the "path" `one/two/` determining the content that is rendered in the
 Page with slug `mypage`.

 Here's a real world example of this rewrite rule in CiviCRM:

 https://github.com/civicrm/civicrm-
 wordpress/blob/master/civicrm.php#L826-L831

 What happens since [47937] is that
 `https://my.domain/civicrm/event/info/?reset=1&id=1` incorrectly redirects
 to `https://my.domain/civicrm/?reset=1&id=1` and therefore breaks the
 rendering of the Page, since the "path" has been cleared.
