[bug] Tauri v2 not able to change "WebView2 Manager" group name in Windows 11 Task Manager:

[wildhart]

Describe the bug

Following on from this Discussion it seems that in Tauri v2 it's not currently possible to change the "WebView2 Manager" group name in Windows 11 Task Manager:

The screenshot above was from a brand new app scaffolded with:

npm create tauri-app@latest my-app2 -- --template vue-ts

Issue #1849 (2021 - Tauri v1), #5611 (2022 - Tauri v1) and #10536 (Aug 2024 Tauri v1) show screenshots of the Task Manager with the process group named after the app, but that no longer seems possible in Tauri v2.

My screenshot also shows Microsft Teams and Search apps which use WebView2 and change the process group name, so it should be possible.

In my discussion, @starkmarkus concluded:

if Windows 11 Task Manager grouping can be influenced, it would likely need a Tauri/WebView2 integration change rather than a bundle metadata change

Reproduction (Windows 11)

1. npm create tauri-app@latest my-app2 -- --template vue-ts
2. run the app
3. Open the Windows Task Manager and search for "WebView2"

Expected behavior

The processes should be grouped under the app name or short description.

I see the same issue on my machine but just for clarification, this is not about renaming the processes (which we can't!) but rather about why the task manager does not group the processes together anymore (the main process, under which the WebView2 process should be attached, should still be in the top of the list correctly named).
As far as i can tell we have not made any relevant changes but the facts that nobody complained in https://github.com/MicrosoftEdge/WebView2Feedback/issues and that MS Teams still is correctly grouped disagree with that assumption 🤔
