Android: Hide handler(s) if the cursor is not visible anymore

On Android if the edit control is bigger than the remaining screen we resize it, this caused the
handler(s) to remain outside the control.

A better fix will be to ensure that the cursor/selection remains visible when the control is resized
but I don't know if this is the desired behavior on all platforms.
