This function seems not touching any state in AccessibilityDetailedView. Can we
move it into cc file in the anonymous namespace.

[xiyuan, 2017/03/28 20:11:25]

Can we pass HoverHighlightView* instead of **?

[xiyuan, 2017/03/28 20:11:25]

nit: I'd call this UpdateCheckMark.

Done.

[minch1, 2017/03/29 01:15:11]

[xiyuan, 2017/03/28 20:11:25]

nit: Can we pass in the string instead?
i.e.
   void AddSubHeader(const base::string16& header);

[minch1, 2017/03/29 01:15:11]

Hi,xiyuan. I guess here is to make the function readable? I changed the function
as following, 
 void AddSubHeader(const base::string16& header_text)
