Hi Team,
We find out another issue in the RichTextEditor about the Header and Footer Section of the page, we have a scenario in which we have a bigger table in the Footer section in terms of height, and the table going just "Out Of the Box". I tried the same table in the header section I found a similar behavior there also but the major issue is the Footer section where it's going out of the page.
I used the demo Winform application to reproduce this, I am also attaching the source file so you have to open it in the editor on your side to reproduce this issue.
Regards
