: Breadcrumb

If I use Breadcrumb-Items with a template instead of text- and icon-attributes, invoking StateHasChanged will throw an Exception.

Here is a minimal excerpt to illustrate the problem:

Snippet

<button@onclick="(ev) => StateHasChanged()">Destroy</button>
<SfBreadcrumb>
  <BreadcrumbItems>
    <BreadcrumbItemText="this works"></BreadcrumbItem>
    <BreadcrumbItem>
      <div>
        <span>@(DateTime.Now.ToLongTimeString())</span>
        invoking StateHasChanged will throw Exception thanks to this RenderFragment
      </div>
    </BreadcrumbItem>
    <BreadcrumbItemText="also works"></BreadcrumbItem>
  </BreadcrumbItems>
</SfBreadcrumb>

This Error will occur in Browser:

This seems to be a Problem with 25.*-versions. If I downgrade to 24.1.*, the Error dissappears and everthing works as it should.

Just a guess: I think, the JsonIgnore-Attribute at Children-RenderFragments are missing in the BreadCrumb(Item)-Controls.

If I'm guessing right: Will this be fixed? Can you provide a rough time-/version frame (rather in the weekly releases or in the next major release)?

Otherwise: Is there a workaround apart from not using StateHasChanges?
