Light Group level not being reflected properly.

[tomnehek]

Hello! Big fan of this card. Though it seems that since the latest big release of Home Assistant, this card no longer handles groups properly.

For example, If I use the slider to change the level of a light group, everything behaves as expected. However, if any of the lights in the group change the slider will not reflect that change. It either does not change at all, or it immediately displays as "off".

The lights listed below the slider are all the lights in the group. As you can see, the slider does not reflect the levels of the lights.

I am running the most recent release - also tried the available beta. Several browsers as well.

Thank you!
