After disabling Rubocop, I did not close the file, instead just used Cmd + Q to quit. Then when relaunching Sublime, the previously opened file was reopened/still open. This screenshot is after a restart and shows the Rubocop line highlighting and the results of Sublime's "Package Control: Enable Packages" (showing the currently disabled packages).
It appears that closing the file and restarting Sublime prevents seeing highlighting after the package is disabled.
This issue was first described in a StackOverflow question since I was not sure at the time what was causing it.

Since then, I think I've narrowed down the issue.
OS: OSX 10.9.1 Build 13B42 Sublime Text : Stable Channel, Build 3059 Rubocop Package: v2014.02.01.19.05.03
