Steps to reproduce:
I am sizing table elements within rows (TD and TH elements) using box-sizing: border-box. This works correctly for my Table when on a page, but does not work correctly when the same Table is within an iframe. It seems that border-box is ignored within the iframe, and content-box sizes are applied instead.
Actual results:
See above. I have created this simple code pen to show the issue. https://codepen.io/turjmner8/pen/eYoppbp
The first Table in the iframe has the same styling and width settings as the second Table that is outside of the iframe, yet the resulting cell widths are all as if content-box sizing was utilized rather than border-box sizing.
Expected results:
My expectation is that both Tables would be sized the way the second Table that is not rendered within the iframe is sized. When I run the same sample in Chrome, Safari, or Edge, both Tables are sized as expected.
This additional code pen example allows for the TD elements to be sized correctly within the iframe, but the TH elements still seem to use content-box sizing for some reason...

The Bugbug bot thinks this bug should belong to the 'Core::Layout: Tables' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

I think this is basically just a quirk. It works if you add <!doctype html> to the iframe.
My guess would be this code, which comes from bug 778413...
Might be interesting to check what the behavior of other engines is. Maybe they removed that quirk?

That is, don't force the width to be content-box. That matches other
implementations and the spec.
