[bug]: `setopt INTERACTIVE_COMMENTS` is not taken into account after setup

[mgkurtz]

Describe the bug

F-Sy-H correctly highlights comments when INTERACTIVE_COMMENTS is set in zshrc and highlights them as ordinary (usually unknown) tokens otherwise. But, when setting INTERACTIVE_COMMENTS interactively, F-Sy-H keeps the old and now wrong highlighting setting.

I fount this, when I issued setopt INTERACTIVE_COMMENTS to fix fast-theme --test /my/own/theme output.

Steps to reproduce

Install fast-syntax-highlighting, and either have setopt interactive_comments in your ~/.zshrc or keep the default of setopt no_interactive_comments. Then change that setting and type a comment.

Expected behavior

Setting the INTERACTIVE_COMMENTS option should also reset highlighting of comments.

Screenshots and recordings
