[BUG] Test list flickers and scrolls erratically during test execution

[magicxor]

Describe the Issue

During the execution of our test suite, the list of tests in the testing interface exhibits unstable behavior. Specifically, the test list constantly flickers and the scroll position randomly jumps up and down. This erratic movement makes it difficult to track the progress of individual tests.

Steps To Reproduce

1. Start the test suite.
2. Observe the list of tests as they run.
3. Notice that the list flickers and the scroll position changes randomly.

Expected Behavior

The test list should remain stable during execution, allowing for continuous monitoring without any involuntary scroll changes or flickering.
