Alert status is resolved, notification email content style is abnormal!

[yimao]

What did you do?
When I receive an email notification that the alert has been resolved, the email content is displayed abnormally.

When I get an email notification that the alert is triggered, the email content displays fine.

What did you expect to see?

What did you see instead? Under which circumstances?
