I was able to reproduce on Sierra Debug with:

run-webkit-tests imported/w3c/web-platform-tests/html/webappapis/timers/type-long-setinterval.html --iterations=100 --no-retry-failure -f --debug -g

This has since started on WK1 as well as iOS.

The test was renamed to type-long-setinterval.any.html and the test expectation was not updated. To me that is evidence that this is no longer an issue, so I'll close this one. Please reopen if type-long-setinterval.any.html starts having issues though.

On further inspection it seems that this test was converted into a JavaScript test during a WPT import and is no longer run.
