Debugging #17931 uncovered a race condition in the way we use the `waitForEvent` function. Currently the following happens: 1. We call `waitForEvent`, which starts execution of the function body and immediately returns a promise. 2. We do the action that triggers the event. 3. We await the promise, which resolves if the event is triggered or the timeout is reached. The problem is in step 1: function body execution has started, but not necessarily completed. Given that we don't await the promise, we immediately trigger step 2 and it's not unlikely that the event we trigger arrives before the event listener is actually registered in the function body of `waitForEvent` (which is slower because it needs to be evaluated in the page context and there is some other logic before the actual `addEventListener` call). This commit fixes the issue by passing the action to `waitForEvent` as a callback so `waitForEvent` itself can call it once it's safe to do so. This should make sure that we always register the event listener before triggering the event, and because we shouldn't miss events anymore we can also remove the retry logic for pasting. |
