Title: Fix #10639 a more robust solution

https://github.com/jquery/jquery/commit/7f6a991313380b74d5fb18782fb6b99fd6c4a22d#commitcomment-835643

From a discussion of a previous fix to this issue, the problem is broader than just percentage margins and affects percentage lengths for a variety of properties in WebKit. This also fixes some incorrect reporting of lengths in IE particularly for top/bottom/left/right.
