Subject: [PATCH] Tests: Import WPT html/dom/aria-attribute-reflection.html
 test
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This change imports the WPT html/dom/aria-attribute-reflection.html test
into being an in-tree test — and deletes the related existing test
from https://github.com/LadybirdBrowser/ladybird/commit/a924e8747a4
previously “ported” from the WPT with changes to run under our (non-WPT)
in-tree test harness.
