Note that this function is also used to check HTTP method, so this will also fix part of bug 46008.

I think that this is unlikely to break web sites. Seems fine to make the change, as long as at least one of IE/Firefox matches the spec here.

Given that we're going to import the whole test suite sooner or later, and that this is such an inconsequential change, it may even be OK to land it without a regression test.
