Buttons blank after updating to 1.6.3 (from 1.5.0)

Describe the bug When running the following code in 1.5.0 you get a button with the text “Info” as expected. After updating to 1.6.3 it is blank (see screenshots).

Application.Init();

var w = new Window();

var btn = new Button
{
    Text = "Info",
    IsDefault = false,
};
w.Add(btn);
Application.Run(w);
Application.Shutdown();

Screenshots Running with 1.5.0

Running with 1.6.3

@BDisp There’s a variant of that test incorporated in #1752 (lines 29 and 169 on in ButtonTests.cs) that catches the issue here if it recurs; I also added your Update_Parameterless_Only_On_Or_After_Initialize test which covers this. We’ve got good coverage of both the Text v TextFormatter desync and consistency between Text/TextFormatter and the resulting display contents with that PR now.
