client.seed callback not called when tab is not focused.

[LucCADORET]

Hi, I am using the WebTorrent Browser version in an Angular app.

From a web-torrent.service.ts, I have a function

  startTorrent(callback: any) {
    this.client = new WebTorrent();
    this.client.seed(this._filesToSeed, (torrent) => {
      this._magnet = torrent.magnetURI;
      callback(torrent)
    });
  }

This function is called from a component, simply like that:

this.webTorrentService.startTorrent(onTorrent)

It turns out that my callback 'onTorrent' is never triggered when the browser tab is not in focus. It will be triggered only when the tab gets the focus again. Is it a normal behavior ?

The issue appears in both firefox and chrome.

I couldn't build a gist to reproduce the error, since there's an error with the client.seed method when you use webtorrent.min.js as-is.
