I would just remove this, it is broken anyway and might bite us. It is quite dangeous resetting the input context behind our backs as it can easily get out of sync, for instance if I have a composition, then this would reset that from the internal state of the input context and it will get our of sync with webcore

Agreed.

Would sound slightly better as showPopupAtCursorPosition().
