Description Chris Dumez 2023-04-24 18:48:16 PDT 
Some streaming sites fail with an Embedded Video Sandbox Browser Error since 255052@main.
255052@main seems correct per the specification but exposing the "Chrome PDF Viewer" caused those sites to use a different code path for validating iframe sandboxing.
They now try to load a data URL with a pdf MIME type inside an <object> element and this fails on iOS.
