Textbubble doesn't show up at all

The problem

Describe the bug
Attempted to experiment with the Textbubble style, but even at its most basic settings, it does not appear, no matter what I do.

To Reproduce
Steps to reproduce the behavior:

1. Create a new timeline and character.
2. Create a new (default) premade Textbubble style.
3. Add one or more Text commands.
4. Play the timeline using the button in the Dialogic extension or run a start_timeline() command.
5. Observe that no bubble appears.

Screenshots
If applicable, add screenshots to help explain your problem.

System (please complete the following information):

• OS: Windows 10
• Godot Version: 4.4 (also checked 4.3)
• Dialogic Version: 2.0-Alpha-16

Thoughts

EDIT: Originally I wrote down a theory of my own as to what was going wrong, but then I downgraded to Alpha15. This not only fixed my issue, it also completely invalidated my theory - so I'm removing it for clarity.

Don't know why GitHub opened this twice. Either way, downgrading to Alpha15 fixed the issue.

Couple of notes:

• Use start() instead of start_timeline() if you want a style to be added
• you need to register characters to nodes that the bubble points at

But I will test this again and see whether it is actually broken.

As this is my first time playing around with the bubble, I did not know about the instructions in the fallback bubble. After downgrading, I was made aware of registering characters. If so, maybe the issue should be "fallback bubble does not appear in Alpha16"
