[GTK?] Controls don't have the proper default values until they get loaded

[Miepee]

Expected Behavior

Some controls have some different default values that I'd expect to be set after initializing the control.

Actual Behavior

The default values don't actually have any effect until the form(?) gets loaded.

Steps to Reproduce the Problem

1. Create a new control (i.e. label)
2. Try to print its visibility

Code that Demonstrates the Problem

public MainForm() {
var label = new Label();
Console.WriteLine("beginning " + label.Visible);
label.Shown+= (_, _1) => Console.WriteLine("shown " + label.Visible);
label.PreLoad += (_, _1) => Console.WriteLine("preload " + label.Visible);
label.Load += (_, _1) => Console.WriteLine("load " + label.Visible);
label.LoadComplete += (_, _1) => Console.WriteLine("loadcompete " + label.Visible);
Content = label;
Console.WriteLine("end constructor " + label.Visible);
}

Specifications

• Version: 2.7.3, 91a4744813108d127ec697e03a74d9c102eecdf5
• Platform(s): GTK

• Operating System(s): Arch Linux

  Additional Information

  This may or may not be related to #2095 . I just discovered this, because the "StylesShouldApplyWhenControlDynamicallyAdded" tests have the same setup, (i.e. create label, assert on its visibility)
