> *Logical summary*:
> * squiggly is set to spell check when the focus returns to a text field (see SpellUI.handleFocusIn())
> * after making changes to the text, the RichEditableText's textFlow is damaged and has to be recomposed. This normally happens in the next frame, when RichEditableText.updateDisplayList calls _textContainerManager.updateContainer().
> * BUT if we set focus on the RichEditableText after the text change, squiggly does the spell checking on the damaged textFlow.
> * because of this, it's offered bad indexes in SpellUI.getValidFirstWordIndex() and SpellUI.getValidLastWordIndex(), thus checking on non-existing text.
