Button callback not invoked

[HaSa1002]

The button callback gets not invoked on Windows. Maybe I am stupid (I am just toying around with zig and capy and learn as I go).

const std = @import("std");
const capy = @import("capy");
pub usingnamespace capy.cross_platform;

pub fn main() !void {
    try capy.backend.init();
    var window = try capy.Window.init();
    window.setPreferredSize(600, 800);
    window.setTitle("ArtGit");
    std.debug.print("Hello?", .{});
    try window.set(capy.Button(.{ .label = "Some text", .onclick = onButtonClicked }));
    window.show();
    capy.runEventLoop();
}

fn onButtonClicked(button: *anyopaque) !void {
    std.debug.print("wow", .{});
    var btn = @as(*capy.Button_Impl, @ptrCast(@alignCast(button)));
    btn.setLabel("Was clicked");
}

Observed behaviour

Window is created, the button has the label "Some text" and on click nothing happens.

Expected behaviour

Windows is created, the button has the label "Some text" and on click "wow" is printed and the label text is set to "Was clicked".

Sys Info

Windows 10 Zig: 0.11.0-dev.3937+78eb3c561

Window doesn't process BN_CLICKED directly on Windows now, wrapping the button with a container will work as a workaround.

try window.set(capy.Row(
    .{ .wrapping = true },
    .{capy.Button(.{ .label = "Some text", .onclick = onButtonClicked })},
));

Yeah I did that later, but the getting started guide does so hence the confusion. It should get documented probably?
