 Steps to reproduce:

 1. Open web UI with some build.

 2. Click on "download log as file".

 Expected behavior: browser download menu appears and nothing changes on
 page.

 Observed behavior: browser download menu appears, in the background I see
 green message "Connection restored" and page reloads.

 Happens in Firefox. In Chromium raw log downloads without page reloading.
