I save a rich text in a text type in the database.
-When I display it in the rich text editor, it looks fine.
-But when I pull the data to a text element. (have not clicked cut of content), it only shows the first 16 rows.
Create a sandbox page, place only a text element, try different text heights (just to see … it is not really necessary), try again and see if it happens again.
Please note that I am displaying 30 paragraphs, 2753 words of ipsum lorem text with no problem and no worries about text height:
