+
+            Revision 207483 caused the touch bar to stop showing up in HTML Notes due to -updateTextTouchBar not
+            initializing the text touch bar and causing -makeTouchBar to return nil while processing a mouse click. The
+            purpose of bailing out of the update was to prevent the text touch bar from thrashing during a selection drag.
+            If the text touch bar doesn't exist yet, we don't have to worry about its appearance flickering from a different
+            previous state, so we should just allow the touch bar to update instead.
