PerformanceScriptTiming: forcedStyleAndLayoutDuration property

Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The forcedStyleAndLayoutDuration read-only property of the PerformanceScriptTiming interface returns a DOMHighResTimeStamp indicating the total time spent, in milliseconds, by the script processing forced layout/style. See Avoid layout thrashing to understand what causes this.
