描述

https://drafts.csswg.org/cssom-view/#the-screen-interface

availWidth and availHeight are in the spec, but not availLeft or availTop.

Those two attributes are in Chromium, Gecko and WebKit, but not EdgeHTML.

There are 24,256 hits in httparchive for 'screen.availLeft', enough that I didn't try looking at how they're used.

研究方向
Review the CSSOM View draft (https://drafts.csswg.org/cssom view/) for the Screen interface. Examine current implementations of availLeft and availTop in Chromium, Gecko, and WebKit to understand existing behavior. Analyze usage data from Chrome Platform Status links provided in the issue. Propose adding these attributes to the spec with consistent definition and cross browser compatibility notes.
