+/*
+ * This scenario currently shows somewhat unexpected behavior from the PoV of a user:
+ * The error is dropped, but the recording is started and continued anyway.
+ * If folks only sample error replays, this will lead to a lot of confusion as the resulting replay
+ * won't contain the error that started it (possibly none or only additional errors that occurred later on).
+ *
+ * This is because in error-mode, we start recording as soon as replay's eventProcessor is called with an error.
+ * If later event processors or beforeSend drop the error, the recording is already started.
+ *
+ * We'll need a proper SDK lifecycle hook (WIP) to fix this properly.
+ * TODO: Once we have lifecycle hooks, we should revisit this test and make sure it behaves as expected.
+ *       This means that the recording should not be started or stopped if the error that triggered it is not sent.
