fast/canvas/webgl/gl-get-calls.html incorrectly puts xmlns="http://www.w3.org/1999/xhtml" in its html tag, which causes it to be treated as xhtml when using libsoup (as used on the Gtk and WPE backends). As it isn't well-formed, this causes the test to fail.

I would call this a real bug in these ports, as content sniffing local files is no less dangerous than content sniffing resources served by HTTP. This file just shouldn't be parsed as XML. Also, there is an explicit meta http-equiv that should be respected when content sniffing.
But it's OK to correct the test.

HTML5 doctype is "<!DOCTYPE html>" (lower case).
