This is an interesting bit of trivia and fun to know, but I beg front end devs: PLEASE do not take this as anything more than an interesting bit of trivia. <i>Please do not</i> incorporate this information into your workflow; it would be pure folly as it introduces complexity, potential confusion, and potential bugs and yields infinitesimally small returns.<p>Thank you mathias for writing about this, it's neat to know how these things work!
