Volume control applet changes volume to 100% when a notification occurs

[martinvonwittich]

Expected behaviour

1. Opening the volume applet and changing the volume by dragging the slider with the mouse should not set the volume to 100% when a notification occurs.

Actual behaviour

1. Volume is set to 100% :(

Steps to reproduce the behaviour

1. Run the following command in the terminal to trigger a notification in 5 seconds:

   sleep 5; notify-send foo

2. Open the volume applet and click and drag the slider. Keep the mouse button down.

3. Wait for the notification ot occur, and notice that the volume slider jumps to 100%.

I was unable to duplicate this (following your exact instructions) with current mate-media 1.23.0 from git master. I tested both the status icon and the newer panel applet and neither one jumped the volume when the notification came up with the mouse button still down on dragging the slider

@lukefromdc thanks for attempting to reproduce it! If this is already fixed, I'll just wait for the next Ubuntu LTS release.
