Cannot process pending renders after the renderer has been disposed.

[vd3d]

Hi,

I got an error : Cannot process pending renders after the renderer has been disposed.

It is when I start the application.

I noticed that if I only use the "Title" tag, it works.

Some code

Really nothing special... but

context.Services.AddHeadElementHelper();
app.UseHeadElementServerPrerendering();

It is because of the data-app="true" !

@vd3d Could you tell me why you need to add the attribute "data-app=true" into the "meta" tag?

Adding support to accept any attributes is very hard work because this is NOT a simple Blazor component but to save, transfer, and restore complex information between server and clients.

Therefore, I want to know how important adding support to accept the attribute "data-app=true".
