Message indicator (group chat) on taskbar icon doesn’t vanish properly

Miranda Version                  : 0.9.2
Unicode Build                    : Yes
Test Build # (if applicable)     : none
Plugin Version # (if applicable) : 2.9.0.4

What steps will reproduce the problem?
1. Leave open group message window with at least two tabs. Chatroom #1 is 
active.
2. Set the focus to some other window.
3. Someone writes a message in chatroom #1.
4. You click on the chat window to bring it into focus.

What is the expected result?
The taskbar icon from chatwindow displays an overlay indicator because of the 
new message in the active chatroom. If you bring the chat window into focus, 
the overlay should vanish.

What happens instead?
The overlay does not vanish directly. You have to select another tab to do so. 
If there is only one tab open it never vanishes until the window is closed.

The bug shows also in another form: If someone writes in chatroom #2, which 
wasn’t the active tab, the taskbar icons does not show the overlay at first. 
But if you select the tab for chatroom #2, it shows. Again it only vanished 
until selected another tab or close the chat window.

Please attach or post your VersionInfo.
The same as in issue #928.

Maybe this bug is considered as a feature, but I don’t get it. The indicator 
in taskbar should vanish, when I get the chatroom into focus to read.
