cutiePI shell browser can not cast to chromecast device?

[imaclmaca]

The browser window of the cutiePi shell does not seem to have the ability to chromecast - the version of chromium on the desktop version does, however.
Since HDMI output seems a bit flaky, I was looking at using the chromecast to get media up on the big screen, but that only works from the desktop, which is fine.... but not what I had hoped to do...
