Netmonitor Remote Address is always 0.0.0.0 localhost

TorBrowser 6.5.2 on Linux

=== To reproduce:

1. Open Inspect Element -> Network
2. Visit a new site, e.g. https://trac.torproject.org/
3. Click on the request entry for the initial request in the inspector.

=== Expected: The "Remote address" field shows the IP address of the site returned by the DNS query. This is the behaviour in Firefox.

=== Actual: Remote address is always shown as 0.0.0.0
