Version: Chrome beta- and dev-channel (both 50.0.2661.32, I believe), CRD 50.0.2661.22
OS: ChromeOS

What steps will reproduce the problem?
(1) Connect to a host with CRD.
(2) Let the ChromeOS device sleep (e.g. close the lid).
(3) Leave the device alone for a while.
(4) Resume the ChromeOS device.

What is the expected output? What do you see instead?

Expect to see CRD either seamlessly reconnect to the host, or show an indication that the connection was dropped.

Instead it shows a Connecting... dialog with the "Authorize Chrome Remote Desktop" dialog underneath it, and the connection attempt never completes.
