Steps to reproduce:

Take a look at this example: http://jsbin.com/sarozi/edit?console,output


Actual results:

Computed styles of width/height contain size of rendered scroll bars.


Expected results:

Scroll bars size shouldn't be added to computed CSS width & height properties as they are meant to represent content dimensions.

Taking a look at the linked example, this doesn't appear to be an issue anymore in Firefox 120. The computed width and height is unaffected by the size of rendered scrollbars.

I'm new(ish) here and am not sure what the process is for closing bugs, so I am requesting information from :emilio

It happens if you have overlay scrollbars disabled, but it's invalid. width should round-trip. div.style.width = getComputedStyle(div).width shouldn't change rendering.

So our behavior is correct.
