REPRODUCTION:
I was able to reproduce this on macOS 26.4 release ToT with the following:

run-webkit-tests --no-build --no-retry --no-show-results --exit-after-n-failures=1 --expect-pass --iterations=5 --force --release inspector/timeline/line-column.html

I am going to mark expectations as failure while this pends investigation.

This could be a rebaseline.
