Iframes are reloaded when going into DPIP

[saghul]

👋 I was testing the following to see if it would work as a workaround for iframes not (yet) being able to request DPIP:

• Top level document has an iframe inside a div with id "container"
• Put the "container" div into DPIP

Expectation:

• The iframe would move into the new PiP window, as if nothing happened?

Result:

• The iframe is reloaded

Some other observations:

I can kind of understand the behavior, if we consider that window.parent for the iframe would change. I assume, thus, that the iframe's parent window would be the PiP window, and thus some extra code would be necessary to communicate with the iframe, once it moves to the other window, correct?

Has the idea of "seamlessly" transitioning to the PiP window been given some thought?
