Detecting tabs change in Safari App Extension when switching windows inside validateToolbarItem.

Hi. I'm a developer of Tab Finder (https://apps.apple.com/us/app/tab-finder/id6741719894)

My problem is that every time i switch from my first window to a second window, the tabs in the validateToolbarItem() are INcorrect on a first call, but when I switch back from the second window to my main window, the tabs are CORRECT even on a first call.

To demonstrate it, i recorded a video: https://youtu.be/RwskzrSJ8u0

To run the same sample extension from the video, you can get the code from this GitHub repo: https://github.com/kopyl/test-tabs-change Its only purpose is to log URLs of an active page of all tabs.

The SafariExtensionHandler's code of the sample app is very simple:

import SafariServices

func printOpenTabsHost(in window: SFSafariWindow) async {
    let tabs = await window.allTabs()
    
    log("Logging tabs for a new window: \(window.hashValue)")
    
    for tab in tabs {
        let page = await tab.activePage()
        let properties = await page?.properties()
        let url = properties?.url
        log(url?.absoluteString ?? "No URL")
    }
}

class SafariExtensionViewController: SFSafariExtensionViewController {
    static let shared = SafariExtensionViewController()
}

class SafariExtensionHandler: SFSafariExtensionHandler {

    override func validateToolbarItem(in window: SFSafariWindow, validationHandler: @escaping ((Bool, String) -> Void)) {
        Task {
            await printOpenTabsHost(in: window)
        }
        validationHandler(true, "")
    }

    override func popoverViewController() -> SFSafariExtensionViewController {
        return SafariExtensionViewController.shared
    }

}

Could you please tell if i'm missing something and how to see the actual tabs inside the overridden validateToolbarItem call of the SafariExtensionHandler (or in any other way, I'm okay with any implementation as long as it works).
