Boolean spread gamma ui editor bug

within a class implementing an interface. nothing special.
gamma preview-0300.

it seems the gamma UI editor has a bug in editing a spread of boolean:
you can change the spread count but it jumps back (to default) as soon as you get out of the editing state.
boolean spread gamma editor bug

the weird thing is that at some point it started to work…
…maybe after I created a similar spread iobox in the main patch (where it was working) and copied over in the class?
I cannot reproduce now

Maybe related

Thanks, fix in upcoming.
