Issues with domain reload and configurable play mode options

[Tavrox]

Hello !

There are static variables that make this tool hard to use with Play Options (Experimental) around Domain Reloading.

Configurable play mode :

Check out :

Repro :

• Launch the game in editor
• Cancel the play with play button
• Relaunch play fast (thanks to domain reload)
• The debug menu is hard to relaunch

I think the faulty static variables are those one :

	#region Static Public Methods

	public static EventArgs OpenBranch => new EventArgs { Tag = EventTag.OpenBranch };

	public static EventArgs CloseBranch => new EventArgs { Tag = EventTag.CloseBranch };

	public static EventArgs Repaint => new EventArgs { Tag = EventTag.Repaint };

	#endregion
