Hello,
I am using the Blazor Web Report Designer on a page that is not the default route, i.e. "/". When I am at step 2 in the WebServiceDataSource wizard to add parameters, if I click the Add Parameter button it routes to the home page.
I believe this is caused by the href="#' empty route. Below is an animation of what I mean. This is also reproduced in the BlazorIntegrationDemo in the installation directory.
