* STEPS TO REPRODUCE
1. Inspect any page (make sure the Network tab is not visible)
2. Find a link within WebInspector
3. Right click the link
4. Select "Open/Reveal in Network tab"

Looks like my "solution" for <https://webkit.org/b/190766> didn't work :(

Based on what I can tell, it appears that `this._waterfallTimelineRuler.secondsPerPixel` is NaN.  I'll have to dig around to see how that's possible 🤔
