Flickering when disposing WebView control

Description
We have a problem when adding / remoing Tabs in an TabControl - during removing the tab / disposing the webview control it sometimes happens that the WebView2 control is flickering - please see attached video - https://www.screencast.com/t/YYYEXbtwUoI

We use Microsoft.WebView2.FixedVersionRuntime.87.0.664.41.x64 and WebView2 release version 1.0.664.37.

In code we simply do:

    private void button1_Click(object sender, EventArgs e)
    {
        var page = new TabPage("WebView2 Test");
        page.Controls.Add(new WebView2() { Dock = DockStyle.Fill });
        this.tabControl1.TabPages.Add(page);
    }

    private void button2_Click(object sender, EventArgs e)
    {
        var page = this.tabControl1.TabPages[0];
        this.tabControl1.TabPages.Remove(page);
        page.Dispose();
    }

Version
SDK: 1.0.664.37.
Runtime: 87.0.664.41.x64 fixed version
Framework: WinForms
OS: Win10

Additional context

AB#30943503

Start with the WinForms reproduction shown in the issue: add WebView2 controls to TabPages, remove the first page, and dispose it using the listed SDK and fixed runtime versions. Investigate the flicker during tab removal and disposal; done means the WebView2 control can be removed and disposed without flickering.
