ImageDecoder: reset() method

Limited availability

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

Secure context: This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.

Note: This feature is available in Dedicated Web Workers.

The reset() method of the ImageDecoder interface aborts all pending decode() operations; rejecting all pending promises. All other state will be unchanged. Class methods can continue to be invoked after reset(). E.g., calling decode() after reset() is permitted.
