AdvRichTextEditor probkem

I just updated to the latest download to use in Delphi 11.2 and I am getting an integer overflow error on line 3443 of unit AdvRichEditorBase.

LineHeight := LineHeight + TopLine + BaseLine;

The values for LineHeight and TopLine at that point are very large integers so an overflow is not unexpected. In the I have set the properties to rather ordinary sizes.

A bug or have I done something obviously wrong?



How can this be reproduced?
