Validator parses multiple browser contents as an error in X-UA-Compatible

Hello,
I believe the parsing of meta elements with hhtp-equiv attributes is incorrectly doing a strict parse for "IE=edge" instead of a parse for other forms of the edge browser, including the edge browser and other browsers.

This was a single page validation of part of an online course (that is not yet online) and I noticed it is reading our Edge AND Chrome content as not including "edge"; but it clearly does include both. This could be due to the capitalization of Edge  or possible the addition of chrome?
Thank you!
