Max number og hardware contexts between tabs

Hello,


I don’t understand why the max number of contexts is aggregated between two tabs.


1. On one page I am creating 4 Audio contexts.
2. I am opening a tab from this page
3. On the new tab I am creating 4 Audio contexts.

Results:
Failed to construct 'AudioContext': number of hardware contexts reached maximum


Here is a repro:

Tested on Chrome 36




Is there a way to overcome this - weird -  limitation?




Thanks.
