Description Joseph Pecoraro 2019-03-22 18:49:23 PDT 
Page Weight indicator clears on pages with zero length resources (macrumors.com)

Steps to Reproduce:
1. Inspect macrumors.com
2. Reload
  => Page weight indicator eventually becomes "–" instead of a total value

Notes:
• A NaN creeps in from a resource with a body length of zero.

Err, this should have been `!isNaN(...)`. But I'm just using this first patch to get results from the bots.
