FilePicker's save_file method not working as expected

[mvwilpe]

It seems that FilePicker's the save_file isn't working as expected.
e.g.
file_picker.save_file(
dialog_title="this title is ignored",
initial_directory="/this/works",
file_name="this name is ignored",
file_type=ft.FilePickerFileType.IMAGE
)

So the file name is ignored, (i.e. left blank in the OS file dialog)
but if the file_name specifies a full path, the specified path for the initial_directory is ignored (but name is still empty).
Also setting the dialog_title has no effect but perhaps thats a Linux thing?
(file type works, saving the file - after the name is entered manually in the file dialog - works)

(using Ubunt 24.04)

Works normally on mac:

Might be a Linux-specific issue?

Then probably an Ubuntu 24.04 issue since it used to work on 23.11.
