Bug 168357 – [Resource Timing] Media resources have multiple PerformanceResourceTiming entries

• Status: NEW
• Component: Media

[Joseph Pecoraro]

[Resource Timing] Media resources have multiple PerformanceResourceTiming entries

I need to sort out what to do here. Our behavior may be okay, and if it is I should update tests to be more lenient.

This may involve clarification in the spec and agreement across multiple browsers:
<https://github.com/w3c/resource-timing/issues/100>

Test: imported/w3c/web-platform-tests/resource-timing/rt-initiatorType-media.html
Currently under review at: https://bugs.webkit.org/show_bug.cgi?id=168086
Steps to Reproduce:
1. <video src="..."> / <audio src="...">
2. js> performance.getEntriesByType("resource");
  => multiple entries for the media element

http/wpt/resource-timing/rt-initiatorType-media.html is flaky [Pass Failure] on GTK since long ago, I'll mark it as such.

[Fujii Hironori]

http/wpt/resource-timing/rt-initiatorType-media.html is flaky failure for all platforms.
