I created a PPT file with a single Paragraph with the line "a b c". The a, b, and c are all the same font height. The two spaces are a different height, but the same as each other. When I replace the text on the Portion that contains "b", with an empty string, everything on the slide is blanked.
I was able to workaround this issue by setting the font size for all the portions to be the same height in the PPT template. Is this something that I am doing wrong?
I attached a small test program that shows the issue. I am using Aspose.PowerPoint for Java version 18.104.22.168.
