Issue with Arabic Translation Accent in Edge PDF Reader

I am experiencing an issue with the PDF Reader in Microsoft Edge when using the "Translate selected text" feature.

While the translation functionality works, the Arabic translation is being rendered in Tunisian or Moroccan dialects rather than Standard Arabic (Fusha). This is problematic because Arabic has many regional accents, and the dialects shown are not appropriate for formal or general use.

This issue is inconsistent—sometimes the translation appears in Standard Arabic, but more recently, it defaults to the Tunisian dialect. My system language and regional settings are configured to Arabic (Saudi Arabia), so I would expect the translation output to reflect Standard Arabic or at least offer an option to choose the preferred Arabic dialect.

I would appreciate if you could look into this or provide guidance on how to set the translation to Standard Arabic consistently.

Thank you for your support.
