Lua highlight is broken after the comment

[DifferentialOrange]

Lua syntax local keyword highlight is broken for a line if preceding line is a comment. Reproduces both on Mozilla Firefox and Google Chrome for Ubuntu, as well as Google Chrome for Android.

Examples:

function also breaks up, so it's safe to assume that next keyword is always broken
