REPRODUCIBILITY:

I was able to reproduce this bug on macOS Ventura ToT running the test as follows:

run-webkit-tests --clobber-old-results --ios-simulator --iterations 5 --verbose imported/w3c/web-platform-tests/css/css-text/word-break/auto/

REGRESSION:

This bug started with a the implementation of `word-break: auto` at 265671@main. The passing test expectation was set at 266656@main, which is what triggered this unexpected failure.
