Can lodash debounce cancel a leading-edge invocation before it executes?

Goal: ensure that a debounced function can be fully cancelled, preventing any execution (leading or trailing) even after the first call.

Current lodash _.debounce provides a cancel() method that clears the pending timer, but if the function was invoked on the leading edge (leading: true) before cancel is called, the ongoing call proceeds unaffected.

Uncertainty: should cancel also prevent a leading-edge invocation that has not yet executed, or must users avoid leading:true when they need full cancellability?

Specific questions:

• What options exist to cancel a leading-edge debounced call before it runs?
• Should lodash extend cancel to also block leading-edge executions?
• Is there a recommended pattern to achieve full cancellation without disabling leading edge?
