Can we move the `((webView.get().window._childWindowOrderingPriority == NSWindowChildOrderingPriorityPopover) || [NSUserDefaults.standardUserDefaults boolForKey:@"LULookupDisabled"])` to a variable outside this loop so that it doesn't have to be recalculated in each iteration?
```

bool isPopover = m_webView->get().window._childWindowOrderingPriority == NSWindowChildOrderingPriorityPopover;
bool isLookupDisabled = [NSUserDefaults.standardUserDefaults boolForKey:@"LULookupDisabled"];

for (auto& item : items) {
    if (item.action() != ContextMenuItemTagLookUpInDictionary || (!isLookupDisabled && !isPopover))
        filteredItems.uncheckedAppend(item);
}
```

It looks like you’ll need to add NSWindowChildOrderingPriorityPopover to NSWindowSPI.h as well.
