RM392848Microsoft Edge: v.140 - Auto-discarding Sleeping Tabs

Tabs that have been sleeping for a long time will be discarded to save memory. When a user navigates back to a discarded tab, the tab will need to be reloaded. This can be managed through the AutoDiscardSleepingTabsEnabled policy. This policy will be enabled if the SleepingTabsEnabled policy is enabled.
