Comment (by oandregal):

 > A static variable doesn't persist between runs. You don't need an extra
 parameter to clear it.

 What if the variable is initialized before a "change of theme" such as the
 `switch_theme` or `start_previewing_theme` hook? An easy way to see how it
 fails is by removing my last commit or removing and observing the dozens
 of PHP unit tests failures.
