From 10bdd912d64a45d8b445f33cd10e498d8c071e56 Mon Sep 17 00:00:00 2001 From: Daniel Aleksandersen Date: Sun, 21 Apr 2019 04:48:19 +0200 Subject: [PATCH] Treat meta[property] as a space-separated list (#10604) The @property attribute in HTML is a space-separated list of values. This change normalizes whitespace and finds the desired value in the list instead of requiring an exact single-value match.
