Description
Hi,
We embedded a Vaadin AP in an iframe html such as:
<html><iframe src=" https://demo.vaadin.com/sampler/#ui/interaction/button" style="WIDTH:100%" height="100%" name="test"></iframe></html>
If open the html twice (two tabs) in the same browser window, and switch between these two tabs, the previous used tab will show "Communication problem. Take note of any unsaved data, and click here to continue."
The problem happened in Vaadin Version 7.7.12 or upper (like Vaddin web), but not happened in Vaadin Version 7.1.10.
If removed iframe name, such as:
<html><iframe src=" https://demo.vaadin.com/sampler/#ui/interaction/button" style="WIDTH:100%" height="100%"></iframe></html>
Everything is fine.
Why the iframe name will affect connection in newer Vaadin version? Any ideas? Many thanks.

Reproduce the communication error using the supplied HTML iframe example with a name, opening it in two browser tabs on Vaadin 7.7.12 or newer. Compare the behavior with an unnamed iframe and with Vaadin 7.1.10; done means the connection behavior is explained and a focused fix or confirmed workaround is identified.
