+Subject: webcodecs: Fix race in VE.isConfigSupported() promise resolution
+
+If the context is destroyed before VideoEncoder calls `done_callback`, bad
+things can happen. That's why we extract a callback runner before doing
+anything asynchronous. Since we hold a ref-counted pointer to the
+runner it should be safe now.
+
