What is the current behavior?
When a line has markup it causes a delay in calling OnLineDisplayComplete in an ActionMarkupHandler. This is because this for loop in the LinePresenter includes the markup characters.

Please provide the steps to reproduce, and if possible a minimal demo of the problem:

• Create a basic ActionMarkupHandler and attach it to the LinePresenter.
• Add a Debug.Log to the OnLineDisplayComplete method.
• Visually compare a line with markup ending in the editor and the delay in the Debug.Log firing.
• You can also see the markup characters in the OnCharacterWillAppear method if you add Debug.Log(line.Text[currentCharacterIndex]) inside.

What is the expected behavior?
OnLineDisplayComplete is triggered when the text is finished displaying.

Please tell us about your environment:

• Yarn Spinner Version: 3.0.1
• Unity Version: 6000.0.44f1

Other information
I tried using a copy of the LinePresenter and looping the attributes and calling DeleteRange on the MarkupParseResult before the text loop but this resulted in no change. Eg:

foreach (var markupAttribute in text.Attributes)
{
    text = text.DeleteRange(markupAttribute);
}

// going through each character of the line and letting the processors know about it
for (int i = 0; i < text.Text.Length; i++) {
    ...
