Code highlight is not updated when interacting with animation checkbox input

[mkfizi]

As per title, code highlight is not updated when interacting with animation checkbox input.

Currently the code highlight only includes animate-pulse class on page load or when reloading the page.

Supposedly when animation checkbox input is checked or uncheck, it should update code highlight.

Fix will be included along with new features. However, as of now I don't have the luxury to work on this.
