BUnit render component to string deadlocks when using in a Blazor context > 1.18.4

I use BUnit to render a component to a string inside a blazor application to support rendering markdown.

Currently i’m using it somewhat like this:

var context = new TestContext();

context.Services.AddFallbackServiceProvider(ServiceProvider);

var rendered = context.Render(ChildContent);
var markup = MarkdownStringUtils.TrimLeftSpaces(rendered.Markup);

var html = Markdown.ToHtml(markup, Pipeline);
_markupString = new MarkupString(html);

All versions after 1.18.4 end in a deadlock rendering the component to html

I guess the crucket is here: https://github.com/bUnit-dev/bUnit/commit/7c156921b5f78023ed435577d1baff6116d4d2f4

I tried to wrap my code into a InvokeAsync etc but still get deadlocked (the render pipeline just never passes Render(ChildContent)).

I know this is not the primary use case for bunit, and i am waiting for the native net8.0 implementation to render a component to a string from microsoft.

Are there any workarounds i could use?

I could provide a small repro if needed.

Great. Still have a few other issues to solve before we make a none-preview release.
