Notify when the TextInput cursorRectangle property changes within pre-edit

Anything that updates the horizontal scroll is also likely to change the
position of the cursor rectangle and the micro focus.  So group these
actions together and ensure they're done before emitting
cursorPositionChanged() so positionToRectangle() returns a valid value
from that handler.
