RFR: 8356145: ListEnterExitTest.java fails on macos [v2]

[Abhishek Kumar]

> Test was failing on macOS 14.7.1 system in CI pipeline. Logged output suggests that the mouse exit event is not triggered and thus the test fails.
> Increased number of list items and adjusted the X and Y offset for mouse move events, so the mouse pointer will be within the frame and added robot delay to stabilize the test.
> 
> Verified the updated test in CI on macOS 14.7 machine and there is no failure.
