Here is a profile of resizing a browser window and then deactivating and reactivating the window twice: https://share.firefox.dev/3c71ZO8
There's a lot of activity in the Privileged Content process that restyles/reflows/repaints an about:newtab page for all resize activate/deactivate event the parent process receives.
From the Browser Toolbox, if I execute gBrowser.preloadedBrowser.hidden = true
then the Privileged Content process remains quiet when I resize the browser window.
