	<pre class=prod><dfn>&lt;filter-function></dfn> = ''blur()'' | ''brightness()'' | ''contrast()'' | ''drop-shadow()'' | <br>
	''grayscale()'' | ''hue-rotate()'' | ''invert()'' | ''opacity()'' | ''sepia()'' | ''saturate()''</pre>

This commit changed the definition to:
blur( ) | brightness( ) | contrast( ) | drop-shadow( ) | grayscale( ) | hue-rotate( ) | invert( ) | opacity( ) | sepia( ) | saturate( )

Effectively making arguments invalid for all of these.

Likely an unintended change @tabatkins?

@tidoust reverted that change in #13380, so they are linked again.
@romainmenke With that fix I think it's fine to close this issue. Let me know if you disagree.
