Subject: [PATCH] Fix a scrolling glitch when the editor is updated before
 first measure

FIX: Fix an issue where dispatching an update to an editor before it measured itself
for the first time could cause the scroll position to incorrectly move.

Closes https://github.com/codemirror/dev/issues/1366
