Confusing documentation for highest-available-document-mode

[Andrew-Cottrell]

The page https://webhint.io/docs/user-guide/hints/hint-highest-available-document-mode/#what-does-the-hint-check currently says

By default, the hint checks if the X-UA-Compatible response header is sent with the value of IE=edge, and that the meta tag isn’t used.

My website follows the above rules, but fails the test. I guess the test is actually doing a case-sensitive match on "ie=edge". If this is the case, it should be modified to do a case-insensitive comparison. The X-UA-Compatible header isn't case sensitive and examples use the value "IE=edge".

Can you please share your configuration or is this with the online scanner?
The hint will tell you to add it or remove it depending on your browser support matrix and IIRC the configuration in the online scanner doesn't take into account IE11 (and thus telling you to remove it).

[Andrew-Cottrell]

I was using the online scanner, at https://webhint.io/scanner/, with the Chrome 79 web browser.
If this hint may depend on certain circumstances, perhaps the online documentation could specify.

It's actually in the documentation but a bit buried in the configuration section (it took me a minute to find it and only because I was positive it was somewhere 😓).
We should definitely mention that earlier on to avoid confusion.

Thanks for catching this!
