test list for reproduction

Description:
inspector/dom-debugger/attribute-modified-style.html

The first timeout that I see this on the dashboard was 10/10/2019 at r251000, but does not appear to be relevant to what would have caused this.
The test appears to have landed flaky timeout and continued throughout history.  The approximate frequency appears from once or more a day to every 3 days.

The test averages about 70s on flaky timeout.  The range I see on the dashboard is approximately from 34s to 870s.  
The test consistently passes on Mojave+ release wk1, but flaky timeout on Mojave+ debug wk1.  The test is a flaky timeout on Mojave+ wk2.
