The highlighting of the 'Home' menu-link does not respect query strings and fragment identifiers

It appears this is not related to the issue as was assumed in (#1 - #11):
PathMatcher::isFrontPage() does not work for the default homepage if it contains a query string.

I have tested this with a small block that displayed the value of PathMatcher::isFrontPage(), but it also appears to affect the menu system (where I first noticed this):

Issue since #12:

1. Visit the regular front page of your Drupal site: example.com.
2. Append a query string to the url: example.com?foo=bar.
3. Notice that the home menu item no longer has the is-active class.

I could only achieve above behavior with the home page (example.com?foo=bar and example.com/node?foo=bar) and all other paths work as expected, so there appears to be something wrong with this default front page path somehow.
