:AddPromise does not cancel a Promise object returned by Promise.delay

[LDGerrits]

Trove:AddPromise does not cancel a promise object returned by Promise.delay when the trove object is cleaned up or when the Promise object is removed. This is unexpected behavior given the documentation for Trove:AddPromise (i) and Promise.delay (ii):

(i) "Gives the promise to the trove, which will cancel the promise if the trove is cleaned up or if the promise is removed."

(ii) "Returns a Promise that resolves after seconds seconds have passed. The Promise resolves with the actual amount of time that was waited."

I would have expected Trove:AddPromise to cancel the Promise object that is returned by Promise.delay.
