Blazor Activity links on global render vs per-page rendermode are totally different

[davhdavh]

Is there an existing issue for this?

• I have searched the existing issues

Describe the bug

On project with per-page rendermode, the traces are pretty useless.

Microsoft.AspNetCore.Components.Navigate adds links to the route and then stores it in the link store.

aspnetcore/src/Components/Components/src/ComponentsActivitySource.cs

Line 47 in 27fe84d

_componentsActivityLinkStore!.SetActivityContext(ComponentsActivityLinkStore.Route, activity.Context,

However, when an event handler is run, that is in circuit context, which has a DIFFERENT _componentsActivityLinkStore and thus the links it was supposed to add does not exist.

Expected Behavior

On <Routes @rendermode="InteractiveServer" />

and link to page activity in the event activity:

Steps To Reproduce

1. make new blank blazor with aspire and global rendermode.
2. Start project
3. Click Counter link
4. Click Increment a few times
5. Find trace in aspire -> CORRECT
6. convert app to per-page (or just create another with per-page rendermode)
   a. remove global rendermode
   b. add rendermode to home and counter page
7. do 2-5 again -> INCORRECT

Exceptions (if any)

On page level @rendermode
