1196657 - Ctrl+M should not display the tab audio indicator (on mute state) on a non-audio page

Status: RESOLVED INVALID

(Firefox :: Tabbed Browser, defect)

Description

[Camelia Badau [:cbadau], Desktop Test Engineering]

Reproducible on the latest Nightly 43.0a1(BuildID: 20150819030206)
Mozilla/5.0 (Windows NT 6.1; WOW64; rv:43.0) Gecko/20100101 Firefox/43.0
Reproducible on the latest Aurora 42.0a2(BuildID: 20150819004006)
Mozilla/5.0 (Windows NT 6.1; WOW64; rv:42.0) Gecko/20100101 Firefox/42.0

Steps to reproduce: 
1. Navigate to any non-audio page (e.g: https://www.mozilla.org/en-US/).
2. Press CTRL+M (this keyboard shortcut is used for muting a tab).

Actual results: The tab sound indicator is displayed on mute state (even if I'm on a non-audio page). 

Expected results: The tab indicator shouldn't be displayed because we are on a non-audio page. I think that is irrelevant to display the tab audio indicator on a non-audio page (maybe in this tab I will never navigate to a audio page).

This is by design, and we're probably going to make the feature of muting a tab before it plays any audio more discoverable.
