m_compositionNode is not being updated on JavaScript changes to the focused input text field. It has to be explicitly updated using Editor::confirmCompositon(). In Chrome most of the platforms send confirmComposition on mouse clicks which does not really a good idea and it should probably get called automatically on HTMLInputElement::setValue() calls.

On Chrome for Android we were not calling confirmComposition and then cause the Editor::setComposition() do behave weirdly as it was not able to change the node value anymore returning false. It can be checked using Chrome Beta M25 on mobile version of google.com when clicking on the autocomplete suggestion with a little arrow (see screenshot) when there still is a non-empty composition.
