Automatic update from web-platform-tests Replace assert_precondition with assert_implements in paint-timing/ assert_precondition is deprecated (see https://github.com/web-platform-tests/rfcs/blob/master/rfcs/assert_precondition_rename.md). Since PerformancePaintTiming is not an OPTIONAL part of the Paint Timing spec, these tests should use assert_implements. -- Replace assert_precondition with assert_implements in longtask-timing/ assert_precondition is deprecated (see https://github.com/web-platform-tests/rfcs/blob/master/rfcs/assert_precondition_rename.md). Since PerformanceLongTaskTiming is not an OPTIONAL part of the Long Tasks spec, these tests should use assert_implements. -- Replace assert_precondition with assert_implements in event-timing/ assert_precondition is deprecated (see https://github.com/web-platform-tests/rfcs/blob/master/rfcs/assert_precondition_rename.md). Since PerformanceElementTiming is not an OPTIONAL part of the Element Timing spec and EventCount is not an OPTIONAL part of the Event Timing spec, these tests should use assert_implements. -- Replace assert_precondition with assert_implements in element-timing/ assert_precondition is deprecated (see https://github.com/web-platform-tests/rfcs/blob/master/rfcs/assert_precondition_rename.md).
