Mutiple webview in wpf TabControl, only first (visible) will load

Description
I want to load mutiple webpages at same time, so I add a TabControl and Bind a WebView2 control for each TabItem.
When window loaded, only the first tab loaded with DocumentTitleChanged,FaviconChanged events fired.
The other tabs only load after the tab was clicked.

Demo:
You can see the title will only update after tab was activated. ( The icons was get from some public service based on url, not from webview)

I know this maybe a design decision, wish there is some option to allow loading content without make webview visible or some other ways to get title and icon of the webpage before activating the tabs.

Version
SDK: 1.0.1938.49
Runtime: 117.0.2045.36
Framework: WPF
OS: Win11

Regression
Was this working before but has regressed? No
If yes, what version did this last work on?

Repro Steps
Binding WebView control into TabItem's Content.

<TabControl.ContentTemplate>
    <DataTemplate>
        <ContentControl Margin="0" Content="{Binding WebView}" />
    </DataTemplate>
</TabControl.ContentTemplate>

Start with the WPF TabControl.ContentTemplate repro and the linked discussion about WebView2 visibility during initialization. Determine whether WebView2 supports loading hidden tab contents or whether an alternative title and favicon retrieval path is needed; done means documenting or enabling a supported way to populate inactive tabs before activation.
