    main: move pointer-sync-on-restack code here
    
    We call global.sync_pointer() on MetaScreen::restack as a hack to try
    to fix up the hover state after a pointer grab. Previously we were
    doing this in chrome.js, since there was already a ::restack handler
    there anyway, but this isn't really related to the chrome at all, so
    move it to main.js instead.
