TrailingIconClicked not working in Create, works in Classic using inputfield widget

The inputField widget in Create is inferior to the same widget in Classic.

I had used this is Classic and accidentally discovered there are handlers for leadingIconClicked and trailingIconClicked. Although largely undocumented, these work as intended in Classic:

on trailingIconClicked
   answer the text of me
end trailingIconClicked

This code does nothing in Create; in Classic, using the inputField widget, it does what it I says on the tin.

I presume this is an unintended gap between LC Classic and LC Create for nominally the same widget (inputField). The Classic version is superior which is surprising - this is request for parity.
