Description Hossein 2024-09-19 09:58:53 UTC 
Description:
Italic Arabic/Persian text is garbled with some fonts like "B Nazanin". This problem does not happen with each and every font.

Steps to Reproduce:
1. Open attachment

Actual Results:
Italic text in the attachment is garbled. If you choose the text and make it a normal text, the problem goes away. "B Nazanin" font is used in the document.

Expected Results:
Italic text should be rendered correctly, with italic style applied to it. One can make it normal text to see what it should look like.

Reproducible: Always
