Summary

Remove the HTMLFrameElement.width/height attributes, which return the layout width/height of the frame.

Motivation

It's not in the spec:

http://www.whatwg.org/specs/web-apps/current-work/multipage/obsolete.html#htmlframeelement

It's not supported in Gecko and was not supported by Presto.

It is supported in IE11 and WebKit.

Compatibility Risk

<frame> itself is obsolete and used far less than in times past. There's a risk that there is old content that depends on this. The fact that neither Gecko or Presto added support suggests that it's not critically important. Since the attributes are readonly they can't be used to resize frames.

Alternative implementation suggestion for web developers

Use frameElement.getBoundingClientRect().width/height instead.
