Commands/lines in code examples wrongly highlighted as comments

[muzimuzhi]

Version: 3.1.7a

Some normal commands and/or whole lines in code examples are wrongly highlighted as comments.

• page 864, code example for key /tikz/data visualization/arg1 from key, the \tikzset on last line is in gray.
• page 672, first code example in sec. 52.4 Externalizing Graphics, the whole line \usetikzlibrary{external} is in gray.
• More similar cases can be found in sec. 52.

Can we have any idea how to fix that?
