From bb3cd05c64f42795ed8ca6216b2e961f991a10fa Mon Sep 17 00:00:00 2001 From: Nicholas Wylie Date: Wed, 3 Jun 2020 14:53:05 +1000 Subject: [PATCH] Move cursor outside of when inserting HTML When links are pasted into the editor the cursor ends up at the end of the text node inside the parent element. Any text entered is then appended to the end of the link text. Chrome automatically moves the cursor after the end of elements when additional text is inserted, so this change enforces the same behaviour in other browsers.
