Torrent name is missing once download is started

[feross]

The name of the torrent shows up when asking the user to confirm
whether to start the download, but it doesn't show up after the
download has started, which is confusing, especially when coming back
to the tab.

Fixes: #7362

• Submitted a ticket for my issue if one did not already exist.
• Used Github auto-closing keywords in the commit message.
• Added/updated tests for this change (for new code or code which already has tests).
• Ran git rebase -i to squash commits (if needed).

Test Plan:

1. Click any magnet link from https://codepen.io/ferossity/full/qaezaB/
2. Click "Start Download" to start the torrent
3. Ensure that the torrent title shows up at the top of the page

This is a pretty simple change – anyone want to review before I merge?
