Hard to demonstrate as I’m typing on mobile, but String.prototype.split() accepts RegExp so this replace() and the next split() could both be reduced to one step.

Thank you for the review. I have merged the two lines.
I learned a lot this time that String.prototype.split() accepts RegExp. Thank you again.
* String.prototype.split() accepts RegExp. * RegExp's g flag is ignored in split() so that g flag was removed.

Thank you for your contribution @takenspc! 🌟
Sorry for taking such a long time before reviewing this.
I have made some improvements to the logic in DOMTokenList.#getTokenList() to improve its performance. I also merged the code and changed it to follow the new coding guidelines of using Symbol() or # for internal properties instead of "_" as prefix.
… after in DOMTokenList.
Normalize whitespace before splitting text into tokens.
Fixes #1168.
