 #!CommitTicketReference repository="" revision="55564"
 KSES: Allow `filter` property to accept a URL in `safecss_filter_attr()`.

 CSS filters can accept `url()` as a reference to an SVG filter element:
 {{{
 filter: url( file.svg#filter-element-id );
 }}}
 This commit allows for that syntax to be used in inline CSS.

 Original PR from Gutenberg repository:
 * [https://github.com/WordPress/gutenberg/pull/48281 #48281 Duotone: Use
 the style engine to generate CSS for Duotone]

 Fixes #57780.
