Is it possible to download a blob after the preview has been opened in a new tab?

I use the following code to download some binary data (a PDF document) and open result in a new tab :

$.ajax({
    url: this.downloadurl,
    xhrFields: {
        responseType: "blob"
    }
})
.done(blob => {
    var url = URL.createObjectURL(blob);

    //open blob in new tab
    window.open(url);
    
    //additionally, download the document
    var a = $("<a>", {
        href: url,
        download: this.filename,
    }).appendTo(document.body);
    a[0].click();
});

It also download the document automatically because I found out that it’s not possible to download it using the download icon in the preview.
Here is the PDF document preview in Chrome. If I click on download icon :

It will give this :

Is there a way to prevent this ?
It looks like the URL can only be used once.
