Me again 🙂 This time I’m confused by some behavior involving withContext and CompletableDeferred.

This test fails because of the [Failed] exception which is thrown by the exception handler (which mimicks the default behavior on the Android platform by causing a crash).

By completing a CompletableDeferred exceptionally after a timeout waiting for it, the exception gets propagated to the uncaught exception handler. I wouldn’t expect this, given the documentation of CompletableDeferred.completeExceptionally

[Martin Devillers]

Actually, I find it especially strange that the `CompletableDeferred`’s handling of the exception passed in completeExceptionally changes simply due to the fact that await has been called on it, then cancelled. If await isn’t called, then there isn’t any failure.

In case anyone is interested by this, it seems to be the same issue as https://github.com/Kotlin/kotlinx.coroutines/issues/893 (confirmed by testing on the develop branch)
