v3 - Unexpected behavior when stopping and starting dialogue

[dogboydog]

What is the current behavior?
When calling Stop() on the DialogueRunner and then restarting dialogue, and then starting dialogue, the first line of dialogue in the new node is not displayed, and only part of the second line is displayed. This happens whether StartDialogue is called immediately after Stop or after onDialogueComplete is triggered. Waiting a frame or for N seconds after Stop() avoids the issue.

Discovered in the Godot port in this issue, where I observed in the debugger that two calls to RunLineAsync run simultaneously when the issue occurs (screenshots in the Godot issue)
YarnSpinnerTool/YarnSpinner-Godot#86

Please provide the steps to reproduce, and if possible a minimal demo of the problem:
Run the sample scene and click the Normal Bid or onDialogueComplete Bid buttons

What is the expected behavior?
Maybe some of these cases are not expected to work, but I would think at least the onDialogueComplete case should work ideally?
