Button style not recognizing access key

[RichardD2]

Describe the bug

Buttons do not recognize the access key from their assigned content.

To Reproduce

1. Add a button - either a built-in button or a UI button.
2. Assign its content to a string which includes an access key - for example, "_OK".
3. Run the application.

Expected behavior

The button should display the text OK, and recognize the "O" as the access key.

Screenshots

The button displays the text verbatim, including the underscore:

OS version

Windows 11 24H2

.NET version

.NET Framework 4.8

WPF-UI NuGet version

4.0.3

Additional context

The button styles need to set RecognizesAccessKey="True" on the ContentPresenter elements.

The current workaround is to add a global override to the application styles:

<Style TargetType="{x:Type ContentPresenter}">
    <Setter Property="RecognizesAccessKey" Value="True" />
</Style>
