Please describe the bug

When Copilot's primary language is set to Japanese and user receives a message displaying an email address, the email is not correctly parsed

For example... if the markdown text to be parsed is the following...

小堺えみ子の部署はITマネジメント部、会社名はMicrosoft、住所は静岡県、メールアドレスはemikok.it@pqmtprodc1.onmicrosoft.comです。 [1]

[1]: cite:1 "Citation-1"

the email is parsed as メールアドレスはemikok.it when it should be parsed as emikok.it@pqmtprodc1.onmicrosoft.com

I don't believe this is an issue of WebChat but rather an issue with the dependency used to parse markdown text, Markdown-It

The issue is reproducible by copying the first code block into https://markdown-it.github.io/ or https://markdown-it.github.io/linkify-it/

More-so, I believe this is a language parsing issue with Markdown-It's Linkify It which doesn't parse the email correctly

For full language support, I suggest creating a custom "linkify" function or creating a bug for Linkify It

Do you see any errors in console log?

Additional context

No response

Start by reproducing the Japanese example in the Markdown-It and Linkify It demos linked in the issue, then trace how Web Chat parses chat history. Confirm whether the dependency or Web Chat is responsible; done means the complete email address is parsed as an email rather than only the prefix.
