 	<li>intrinsic (min and max) sizing tests for values other than pre-wrap and break-spaces
 </ul>
 
+<p>Tests that need to be updated:
+<ul>
+	<li>intrinsic sizing &amp; pre-wrap. See <a href="https://github.com/w3c/csswg-drafts/issues/3440#issuecomment-465671641">CSS WG Minutes for the behavior change</a>
+</ul>

 <p>Possible addition:
 <ul>
 	<li>coverage of "break-spaces" not as exhaustive as other values. Basic behavior is covered, and difference from "pre-wrap" is covered as well, so this is adequate, but it doesn't have the long list of basic tests that other values got from the CSS2 test suite.
