Bug 222209 – [ macOS Wk 2 ] inspector/debugger/async-stack-trace-basic.html is flakey timing out

• Component: New Bugs
• Status: NEW

[Robert Jenner]

inspector/debugger/async-stack-trace-basic.html

is flakey timing out in macOS on wk2. It is also flakey timing out in EWS, causing EWS to slow down. 

HISTORY URL:
https://results.webkit.org/?suite=layout-tests&test=inspector%2Fdebugger%2Fasync-stack-trace-basic.html

History shows that the timeouts started when this test first started to run on Big Sur at r271039.
