How to remove slint::SharedString last char in slint-ui?

[fluolite]

property text;

// append a ascii char
text += "a";

// remove last ascii char（）
text.pop();

This feature is currently missing.
You'll have to do that in native code

It's also missing on SharedString rust though
something like so should work:

let ch = the_string.chars().rev().next()?;
let newlen = the_string.len() - ch.len_utf8();
the_string = the_string[..newlen].into();

Expect some of the data structures like javascript array(string) to support simple logic only for UI handler
