Chrome Microphone Exploit Gone Public

I came across this interesting exploit of the PC microphone using the Chrome browser:

The person who reported it to Google waited four months before going public with it and Google has yet to fix it. Here's hoping that going public with the exploit will hurry Google up with the fix. It seems that all they need to do is add some kind of indication that the microphone is still active when a pop-under window is displayed.

NOTE: It is easy to protect yourself by not giving websites access to your microphone, but still it seems like it would be easy for Google to fix this.
