getCharacterBoundsOnScreen(int from, int to) failed to get the bounds on screen

Since v0.11.5, the method getCharacterBoundsOnScreen(int from, int to) failed to get the bounds on screen.
eg:

invoking getCharacterBoundsOnScreen(0, 0) throws exception:

java.lang.IllegalArgumentException: This ParagraphText is not the parent of the given shape (CaretNode(name= position=0 paragraphIndex=0 columnPosition=0 Path[elements=[MoveTo[x=0.0, y=0.0], LineTo[x=0.0, y=0.0]], fill=null, fillRule=NON_ZERO, stroke=0x000000ff, strokeWidth=1.0])):
Expected: ParagraphText@1196785562(paragraph=Par[[]; StyledSegment(segment=# Markdown style=[heading])])
Actual:   null

Thank you for reporting.
Unfortunately, I cannot reproduce the exception so could you please provide a simple program that does.
Thanks again.

Just use a long text and let the vertical scrollbar shows, scroll down to hide the first paragraph, then call getCharacterBoundsOnScreen(0, 0) to get bounds in some way, the exception I mentioned will out.

Strange, I still can't replicate it ?

I can't replicate it in a simple demo either, but it does happen in my application, I need to do more research.
