           Summary: RequestAnimationFrameCallback should not be

          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal

Hi Team,

While going through this file randomly I noticed that we can sync-up this bit and match with spec:

WebKit Source: https://github.com/WebKit/WebKit/blob/7071c8fbb1fec810f51c340903edd02b52161caf/Source/WebCore/dom/RequestAnimationFrameCallback.idl#L34

Web Specification: https://html.spec.whatwg.org/multipage/imagebitmap-and-animations.html#animation-frames

Current:

[ GenerateIsReachable=ImplScriptExecutionContext ] callback RequestAnimationFrameCallback = undefined (unrestricted double highResTime);

As per web specification:

[ GenerateIsReachable=ImplScriptExecutionContext ] callback RequestAnimationFrameCallback = undefined (DOMHighResTimeStamp highResTime);

where `DOMHighResTimeStamp` as per: https://w3c.github.io/hr-time/#dom-domhighrestimestamp

It is:

typedef double DOMHighResTimeStamp;

which is not `unrestricted double`.

Just raising so we can fix it.

Thanks!
