Comment (by peterwilsoncc):

 The [https://developer.mozilla.org/en-US/docs/Web/HTML/Element/iframe
 #attr-sandbox sandbox attribute documentation] on MDN is pretty clear
 about this:

 > When the embedded document has the same origin as the embedding page, it
 is strongly discouraged to use both allow-scripts and allow-same-origin,
 **as that lets the embedded document remove the sandbox attribute** —
 making it no more secure than not using the sandbox attribute at all.

 (my emphasis)

 Locking down access to `window.parent` within auto-discovered embeds is
 quite intentional. The `sandbox` attribute's settings were discussed in
 #32522 but it's quite lengthy.
