Force foreground priority for all tabs

This policy controls whether background web content runs at foreground priority.

By default, the browser optimizes resource usage by lowering the scheduling
priority of content in background tabs. This helps improve overall system
responsiveness and performance for the active tab.

If you enable this policy, background web content runs at the same foreground
priority as the active tab, regardless of visibility state.

If you disable or don't configure this policy, the browser determines the
priority of web content based on standard heuristics. For example, content
that is not visible, not playing audio, and not participating in video calls
may be deprioritized.
