`FileChooser` opens, but no `on_accept!` is triggered

[schlichtanders]

Hello, I am currently in the process of finding out how to open the system filepicker from julia. It is quite difficult unfortunately.

using Moustrap, the on_accept! just does nothing in my case

julia> using Mousetrap

julia> file_chooser = FileChooser()
FileChooser()

julia> on_accept!(file_chooser) do self::FileChooser, files
           println("selected files: $files")
       end

julia> present!(file_chooser)

If I now choose a file and click "open", then nothing happens.

Running on nixos with julia 1.10.2 installed via juliaup

@Clemapfel Do you know how to debug this further? What could be the problem ...
