+Subject: Ensure that XRLayer includes base EventTarget in Trace
+
+Trace was skipping a level in the class hierarchy and calling
+ScriptWrappable::Trace() instead. This was likely the result of the
+class inheritance changing in the spec a while back and getting updated
+elsewhere but not here, since it didn't raise any warnings.
+
+(cherry picked from commit 01b6f7e0a70648d7c7302454993f0bf86d5a0241)
