Description (last modified by SergeyBiryukov)

This is a follow-up to #47020.

The minification of jquery.js in [45342] is not compatible with IE<=8.

The error is:

SCRIPT1028: Expected identifier, string or number
jquery.js (4,13727)

It's caused by


because for and class, being reserved words, need to be in quotes.

I know that WordPress 5.2.x no longer supports IE8 (see #47761). However the change has been ported back as far as WordPress 4.5.x ([46027]), which I'm pretty sure is supposed to support IE8.

Thanks for this one @jqz. Apologies that this one fell through the cracks.

A lot has changed in 3+ year, and even IE11 is now unsupported by Microsoft.

I'm going to close this one out as the time to fix this has passed, and with IE8 usage so low (0.015%), it's not something that's a good use of time.
