Yeah, notice that the message mentions the “HTTP header”, not the meta
element. So, somewhere in your Web-server config, there’s apparently
something set up to send this header:

  X-UA-Compatible: IE=Edge,chrome=1

And it should instead be sending this:

  X-UA-Compatible: IE=Edge

But you can’t fix it just by editing the HTML source. You instead need to
change the Web-server config (e.g., if you’re using Apache, in a .htaccess
file, or in the system config file for Apache).
