What happened?

On a web page with lang="fa" attribute, Cascadia Code and Cascadia Mono don't render the following characters correctly:

• U+060D: Arabic Date Separator ( ؍ ): Should be longer, almost like a division sign
• U+066B: Arabic Decimal Separator ( ٫ ): Should resemble a half division sign centered vertically on the baseline
• U+066C: Arabic Thousands Separator ( ٬ ): Should resemble a single quotation mark aligned with the top of the digits

This issue, however, is not specific to web pages. The same happen in Microsoft Word and Microsoft Excel when the text language is set to Persian.

The following image compares the Cascadia rendering with the venerable Arial. The green Arial sample is correct. The red Cascadia Code sample is not.

Here is my test code for reference.
