How to reproduce:

• Install the listed version of xpra
• Start the xpra server with xpra start-desktop --daemon=no --start-child='xterm' --bind-tcp=0.0.0.0:10001
• Open the html client, close your laptop lid (or deactive the browser tab in some other way)
• Open the tab again and you'll be greeted by a grey screen with the following errors in your browser console.

With the 'decode error packet' continuously flooding in.

On the server side there are the following errors:

Client configuration

Refreshing the tab fixes the issue, I intent to use xpra in a production environment so this is not feasible unfortunately.

Thanks in advance!

Please try again with an up to date version of both components.

I don't know what events chrome triggers when you suspend a tab, and I don't have a mac I can use to test it.
