    }

    show()
    {
        this.popover.show();
    }
    
    hide()
    {
        this.popover.hide();
    }
    
    toggle()
    {
        this.popover.toggle();
    }
    
    dispose()
    {
        this.popover.dispose();
        this.popover = null;
        this.#containerDiv.remove();
        this.#containerDiv = null;
        this.targetInput.removeEventListener('click', this.toggleHandler);
        this.showBtnElement.removeEventListener('click', this.toggleHandler);
        this.isDispose = true;
    }
}

I have edit this line,

const targetSheets = styleSheets.filter((styleSheet) => (!styleSheet.href || styleSheet.href.startsWith(window.location.origin)) && styleSheet instanceof CSSStyleSheet && styleSheet.cssRules);

and remove this code :

 || styleSheet.href.startsWith(window.location.origin)

to like this:

const styleSheets = Array.from(document.styleSheets).filter((styleSheet) => styleSheet.href !== null && styleSheet.href.endsWith(this.targetCssName));

so, how can edit the file?
