As far as I understand it (and how MDN and the WHATWG write it), width="100%" is just invalid.

width The intrinsic width of the image in pixels. Must be an integer without a unit.

It seems like style="width: 100%" should be used here.

Is there any update on this? Spread props are super useful but seems like they’re best to be avoided until this gets resolved…
