Comment (by jorbin):

 In [changeset:"61548" 61548]:
 {{{
 #!CommitTicketReference repository="" revision="61548"
 General: Use legacy content properties for CSS icons.

 In modern browsers the CSS content property provides alt text support for
 assistive technology in the form display / alt text. This introduces
 support for legacy browsers that do not support the new syntax.

 CSS content properties take advantage of the CSS cascade and browsers
 ignoring values they don't understand by adding duplicate content
 properties in the form:

 {{{#!css
 content: display;
 content: display / alt text;
 Modern browsers will use the second property, legacy browsers will use the
 first.
 }}}

 Follow-up to [60885] for #63603. Also [61531] and [61547] because unprops

 Reviewed by wildworks, jorbin.
 Merges [61480] to the 6.9 branch.

 Fixes #64350.
