Should we allow "intrinsicsize" to be updated/removed?

Updating/removing "intrinsicsize" may potentially cause an image to resize.

I think the answer should be yes, since other attributes like "width" "height" can all be added/removed/updated and changing those attributes also cause an image to resize.

People may argue this way may allow developers to work around "unsized-media" policy. But we will be changing the behaviour of "unsized-media": when disabled, set default intrinsicsize to be "300 x 150", this way, even removing intrinsicsize attribute will not reset the image to its content size.

WDYT?

Strongly in favor of allowing it to be updated/removed, just as you can update/remove width, height, sizes, src &etc.
