Setting NotifyIcon.TooltipText at runtime doesn't work

[soleon]

Describe the bug

The tooltip text of the notify icon stays unchanged regardless how it is changed at runtime.

The source code doesn't seem to do anything when setting the TooltipText property. The OnTooltipTextChanged handler simply passes the string value to the managed property that's all, nothing is done to the private _notifyIconService.

To Reproduce

Consider the following code snippet:

XAML

<ui:FluentWindow x:Class="Wpf.Ui.Demo.Simple.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:ui="http://schemas.lepo.co/wpfui/2022/xaml">
   <ui:TitleBar>
       <ui:TitleBar.Tray>
           <ui:NotifyIcon Name="NotifyIcon" TooltipText="Default" />
       </ui:TitleBar.Tray>
   </ui:TitleBar>
</ui:FluentWindow>

Code Behind

new Timer(_ => NotifyIcon.TooltipText = DateTime.Now.Second.ToString(), null, 1000, 1000);

Expected behavior

The tooltip text of the tray icon should change when it is updated at runtime.
