Exception thrown with random control types when finding with a timespan

[powerdude]

Describe the bug I have a test that ultimately does this:

        var mainPage = TemplateHost.Create(new ShellPage()); 
        var shell = mainPage.Find<MauiControls.Shell>("MainShell");
        var muscleGroups = shell.Find<MauiControls.ShellContent>("MuscleGroups");

        shell.CurrentItem = muscleGroups;

        var name = await mainPage.Find<MauiControls.Label>("mg1-name", TimeSpan.FromSeconds(30));
        name.Text.Should()
            .Be("muscle group name 1");

An exception is thrown while finding:

Even though it says DatePicker above, the control type is different every time.

Expected behavior no exception

I believe that a disconnected visual tree causes the problem: in other words, it visits a node that has been unmounted thus the native control has been migrated to another node or disposed of. I'm working on a fix.

Can you check out version 2.0.31?

I'm not getting the random errors anymore.
