[Desktop] WebTorrent shows a blank, non-responsive page

[ggrelet]

Description

When clicking on torrent links, WebTorrent shows a blank page with tab title to WebTorrent. The page do nothing more.
Alas, this behaviour happens 95% on the time on redirection-download torrents (thinking /torrents.php?action=download&id=2650964) and 10% of the time on direct .torrent links like on the video below.

Steps to Reproduce

There's no way to reproduce this behaviour deterministically. However, you can try the following:

1. Go to the Ubuntu Alternative Download page, BitTorrent section.
2. Click on any distribution link.
3. Notice the bug OR retry from step 2

Actual result:

Expected result:

The classical WebTorrent page is displayed.

Reproduces how often:

Intermittent issue: seen 1/10 times on direct .torrent files, but 95% of the time on link redirection torrent files (/torrents.php?action=download&id=2650964)
