Virtual desktop session should be usable without frequent disconnects.

What went wrong?
Frequent disconnects (around 5 minute intervals) make this app pretty unusable for current versions of Chrome

Does it occur on multiple sites: N/A

Is it a problem with a plugin? N/A 

Did this work before? Yes Chrome 48 and lower

NOTE: This is NOT a report about the Horizon app from the web store. VMWare's version is VMWare Blast 1.0.0-1045852 build 1045852

I realize this is hard to be overly specific, and that most people won't have a vmware horizon VDI to work with, however this is a serious regression that affects chrome 49 on windows, osx, chromeos, linux, and chromium built from source. I'll try to give as much information as I can to help diagnose.

The ChromeOS update to 49 is when I first started to hit this issue. I was able to use ChromsOS's powerwash+revert to knock back to the previous build, but this is delicate and not maintainable.

On Linux, I have manually installed chromium  48.0.2564.116 to maintain functionality.

Javascript console is not very helpful, but the app logs at the disconnect event are:

Also started a discussion in vmware community: https://communities.vmware.com/message/2589792

I've been attempting to track down the revision where this breaks however I am having difficulties checking out the older revision of the source tree. I'll continue working on this as well.
