 As reported by @maniu in https://wordpress.org/support/topic/wpmceviews-
 update-switching-visualtextvisual-causes-appendchild-js-error

 When switching views between visual and text mode in the post editor the
 visual editor will fail to render upon toggle if a view was currently
 active/had focus when you moved away from the visual mode.

 In previous versions we appear to move the focus in the editor to the
 first point before the view element when we change views.
