Webpages content disappears if you keep MS Edge running for a long time

[githubusername2024]

Describe what you noticed and did

1. Create a security hardened sandbox
2. Run MS Edge and keep it running for at least one hour
3. Tab titles don't disappear. However, when you switch tabs, the entire webpage content becomes invisible.
4. When you refresh the page, you will see the webpage for a moment before it disappears.
5. Newly opened tabs don't have this problem.
6. Win 11 23H2 (or earlier) also had this problem right after it was released.

How often did you encounter it so far?

Every time

Webpages content does not become invisible when MS Edge is running for hours
