WebView not loading content when running trough a screensaver

Description
The webview is not loading correctly when running trough a screensaver.
The exact same executable works when right clicking and choosing "Test".

Version
SDK: 1.0.705.50
Runtime: Stable 88.0.705.68
Framework: WinForms
OS: Windows 10 20H2

Repro Steps
See attached project. WebView2Screensaver.zip

1. Build attached project
2. Rename output .exe to .scr
3. Right .scr and click "Install"
4. Set to 1 minute and click OK
5. Wait 1 minute for the screensaver to start (Exit the screensaver using Alt-F4)

The WebView never loads the requested URL.
It stays stuck on NavigationStarting:

2021-02-16 16:49:45.980 -05:00 [INF] Starting
2021-02-16 16:49:45.990 -05:00 [INF] /s

2021-02-16 16:49:46.287 -05:00 [INF] NavigationStarting

Expected result can be seen by instead right clicking the .scr file and choosing "Test" instead of "install". Or simply by debugging trough Visual Studio.
Logs when running trough "Test":

Additional context
Trying to change the source a second time for a different URL using a Timer sometime works and display the second URL correctly. I can try to provide a project file if relevant but the results are intermittent.

Start with the attached WebView2Screensaver.zip project, build it, and reproduce the difference between the installed .scr screensaver and the right-click Test path on the listed Windows and WebView2 versions. Compare the logged lifecycle and navigation events, especially the point after NavigationStarting. Done means the requested URL loads reliably when launched as an installed screensaver, while the existing Test behavior remains working.
