What information was incorrect, unhelpful, or incomplete?

Here is the complete section:

Ticking during sleep

The specification (Level 2) requires that performance.now() should tick during sleep. It appears that only Firefox on Windows, and Chromiums on Windows keep ticking during sleep. Relevant browser bugs for other operating systems:

• Chrome/Chromium (bug)
• Firefox (bug)
• Safari/WebKit (bug)

More details can also be found in the specification issue hr-time#115.

I don't understand the ramification of these bugs. For example:

1. Should performance.now() be avoided unless my code will only run on Windows Chrome/FF?
2. Is Date.now() almost always abetter choice because, I assume, it doesn't have these bugs?

What did you expect to see?

I expected to understand when performance.now() should/shouldn't be used because of these bugs.

I also expected to find a definition for "sleep," but when I search for that word there are no articles with that title:

And when I submit the search, there are results, but none of them seem relevant:
