From cddceb9dcacc769ffe21470fee928641ba92ec79 Mon Sep 17 00:00:00 2001 From: silverwind Date: Sat, 26 Nov 2022 17:21:13 +0100 Subject: [PATCH] Fix markdown anchor re-clicking (#21931) (#21946) Backport #21931. The hashchange event did not fire on re-click of a active anchor. Instead, use the click event which always fires.
