Toggle Icon background color on custom background color element

[higty]

Hi. Thank you for your great work with splendid treeview.

I have some problem when using this treeview. It is about toggle icon that the background color of it is not good when on custom BackgroundColor element.

Download Sandbox.TreeView project. Change BackgroundColor to Gray.

<?xml version="1.0" encoding="utf-8" ?> <ContentPage xmlns="http://schemas.microsoft.com/dotnet/2021/maui" xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml" xmlns:local="clr-namespace:SandboxTreeView" xmlns:t="clr-namespace:TreeView.Maui.Controls;assembly=TreeView.Maui" x:Class="SandboxTreeView.MainPage">

<ContentPage.BindingContext>
    <local:MainPageViewModel />
</ContentPage.BindingContext>
<ContentPage.Content>

    <ScrollView>
        <StackLayout>
            <t:TreeView ItemsSource="{Binding Nodes}" BackgroundColor="Gray">
            </t:TreeView>
        </StackLayout>
    </ScrollView>

</ContentPage.Content>

Is there any workaround??

    var extendButton = new ImageButton
    {
        Source = Application.Current.RequestedTheme == AppTheme.Dark ? "down_light.png" : "down_dark.png",
        BackgroundColor = Transparent, <----
        VerticalOptions = LayoutOptions.Center,
        Opacity = node.IsLeaf ? 0 : 1,
        Rotation = node.IsExtended ? 0 : -90,
        HeightRequest = 30,
        WidthRequest = 30,
    };

Maybe it is better to set transparent in TreeViewNodeView class?

Yes, you're right, I'll change it like this when I find some time. By the way, PR is always welcome
