Is the direction of regular icon of "Text Number List" wrong?

[liangdrime]

Summary

• Outlook for Mac is using ic_fluent_text_number_list_20_regular in many scenarios, and the released version used in Outlook is 1.1.221.

• This icon displays normal in LTR language.
  

• Then it is mirrored in RTL language, but the number "1,2,3" was flipped that seems not as expected. And we do not provide versions for languages like Arabic.
  

Potential cause

• In the metadata.json of Text Number List of the latest version 1.1.222, the directionType is unique and the singleton is LTR. Looks like this will result in a single language-direction icon for number list.
• After looking into the Content.json of ic_fluent_text_number_list_20_regular which generated in iOS/FluentIcon/Assets/IconAssets.xcassets path, we're providing only one version of language-direction for this icon. So that Xcode can only use this icon and its mirror.
  

Question/Expected

• Is this as by design or a bug?
• Do we need to provide various kinds of icon for LTR/RTL languages, just like what Apple does in SF Symbols?
