WebGL + UNET(or Photon) : Is it worth it?

Hi,

For now i am using PhotonCloud with the masterClient handling the "master server" choices.
As i see UNET is using the same technologie.

I noticed that when the game tab is not currently selected the browser is sending updates only 1or2 times per seconds.
So if the game has "non playing characters" like mine:

If the masterClient switch tabs, the game is totally ruined as the position and behaviors are not really sent anymore, in the worst cases...
