Email notifications for issue comments are missing formatting/style for quotation blocks
Summary
In the email notification that's sent when somebody leaves a comment on an issue, it's hard to distinguish quoted text from unquoted text, which makes it difficult to figure out who said what and follow the conversation.
Steps to reproduce
- Reply to a comment on an issue
- Select some text in the comment you're replying to, copy-paste it into your new comment, and add
>at the beginning of the line to mark it as a quote. On the web, the quoted text is rendered with a distinct style from the surrounding text — the quoted text is gray, and has a gray bar on the left:✅ 
- View the email notification:
- In Apple iOS Mail, the style of the quoted text is the same as unquoted text, it's just very slightly indented:
❌ - In Apple macOS Mail, the style of the quoted text is the same as unquoted text, with a larger indentation:

- In Apple iOS Mail, the style of the quoted text is the same as unquoted text, it's just very slightly indented:

(Unneeded; it's trivial to reproduce from the steps above.)
What is the current bug behavior?
In email notifications, quoted text is almost indistinguishable from unquoted text.
What is the expected correct behavior?
Email notifications should show quoted text using the same style as on the web (gray, with a gray bar on the left), which is distinct from unquoted text (black).
