We recently accidentally broke the "Enable DRM" prompt without realising, so this adds a test that if EME is disabled and is attempted to be used we we prompt the user to enable EME. It is important we don't regress this feature as without it users with DRM disabled (which is our Linux popuation by default) may try to playback DRM protected video and it won't work and there won't be an obvious way to make it work.
