1. Open a test with multiple steps (to be able to scroll them)

2. Add an Execution delay step - it is added at the bottom of the test and is expanded

3. Click on it to mark it and move it up using the arrows to move steps up and down in the test (until the visible steps are scrolled)

4. Once the desired place is reached click to change the value of the timeout. 

Expected: To change the value successfully 

Actual: Test Studio turns in a Not responding state

Note: To avoid the Not responding state collapse the step and move it up or down that way. Once the desired place is reached, expand it and change its value.
