Bug 1523562 [wpt PR 14822] - Named pages in @page selectors do not have a namespace., a=testonly

Automatic update from web-platform-tests Named pages in @page selectors do not have a namespace. Fixes crash when trying to set selectorText of detached @page rules. We only match local name part of the tag, so there should be no behavioral change here.
