inspector/console/timestamp.html

This test is a flaky failure on macOS release builds (nearly completely occurring on wk2, with a single failure at 268297@main on Ventura x86_64 wk1 release).

HISTORY:

https://results.webkit.org/?suite=layout-tests&test=inspector%2Fconsole%2Ftimestamp.html&style=release&platform=mac

TEXT DIFF:

 == Running test suite: ConsoleMessage.Timestamp
 -- Running test case: ConsoleMessage.Timestamp.Basic

REPRODUCIBILITY:

I was able to reproduce this issue on macOS Ventura (13.5, 22G74/arm64) ToT using the following command:

run-webkit-tests --clobber-old-results --verbose --iterations 10 --exit-after-n-failures 1 inspector/console/timestamp.html

REGRESSION:

This test seems to have been flaky since it was introduced at 263261@main.

Correction in description: there is the reported single failure on wk1 in recent history; however, it appears the test was previously more flaky on wk1.
