WithTimeout Annotation does not work

@WithTimeout does not work as expected. It will only affect the error text ("Test timed out (after 2 seconds)") rather than the timing of the test itself.

eg, using the following test:

public class WithTimeoutTest {

    @Rule
    public JenkinsRule jenkinsRule = new JenkinsRule();

    @WithTimeout(1)
    @Test
    public void testFailsAfter1Second() throws InterruptedException {
        Thread.sleep(181_000);
    }
}

Expected Result:

• Test failed after 1 second.
• log message: "Test timed out (after 5 seconds)".

Actual Result:

• Test failed after 180 seconds (JenkinsRule default)
• log message: "Test timed out (after 5 seconds)".
