Does the icon of features frontmatter support image path?

[zhongds]

icon只展示string，有没有办法支持图片路径或者是<img src="xxx" />之类的写法

#1395 After this PR merged, you can use html string like '<img src="xxx" />' here. This feature will ship in tomorrow's nightly version and the official version will ship next week.
