Standalone-offline-local html download file

I'm implementing a feature in my web-app that let users download a ZIP file.

the ZIP file has this structure:

- my-files.zip

    - index.html

    - attachments

        - file1.png

        - file2.txt

        - ...

        - fileN.ext

the index.html is just a list of the attachments:

<!DOCTYPE html>

<html>

    <head>

        ...

    </head>



    <body>

        <ul>

            <li><a href="attachments/file1.png" download="birthday.png">birthday.png</a></li>

            <li><a href="attachments/file2.txt" download="notes.txt">notes.txt</a></li>

            ...

        </ul>

    </body>

</html>

Suppose the user unzips the archive and opens index.html with a browser.

I'm interested in:

clicking on a link should prompt the download (Save as...) dialog

the download filename should be different from local filename

Currently:

Firefox 62/63: it is behaving correctly

Edge 17: it is behaving correctly (incredible)

Chrome 70: clicking on a link makes the browser navigate to the content - it is ignoring the download attribute

IE 11: same as Chrome

Is there a general approach that works with most browsers (even using JS) to achieve this behavior?

Alternatively, is there a specific Chrome quirk/hack?

Thanks
