Running test(s) icon remains gray while test is running

[gps7]

Running single or multiple unit tests not indicating that test is running. Previous version was showing different color on started test indicating that test is running. There are cases when running multiple tests it makes impossible to understand which test is running since display and run order is not always matching. This was different in older version and was always indicating which tests are executed.

Steps to reproduce the behavior:

1. Select any single test which takes more than 20 seconds or event more than a minute
2. Right click on test (the mouse double click was working before, different issue)
3. Click Run menu item
4. Observe the test icon which shown as gray bubble has not changed

Expectation: A clear indication which test(s) are currently running visually in tree view.
