How to prevent Chrome from pausing file uploads when a tab loses focus?

When uploading a file to a some specific website via Chrome on Windows, the upload gets paused after ~1 min if that tab doesn’t have to focus. I need to focus again on the tab for the upload to resume. Is there some way in Google Chrome to “simulate” that focus, i.e. convince the website that tab In which it is open in Chrome has the focus? Note it works fine on almost all sites e.g. Google Drive.
