[webkit-dev] Request for position on hasDroppedEntry in PerformanceObserverCallback

[Nicolás Peña]

Hi,

We'd like to request an official position on a very small addition to
PerformanceTimeline specification. We've added a hasDroppedEntry parameter
to PerformanceObserverCallback, which is in
https://w3c.github.io/performance-timeline/#the-performanceobserver-interface,
and logic for it in
https://w3c.github.io/performance-timeline/#queue-the-performanceobserver-task.
It lets a developer know when an entry has been dropped from a buffer that
the PerformanceObserver cares about. We reached this solution when
discussing https://github.com/w3c/performance-timeline/issues/169 in a
WebPerf WG call.
