In wp-admin-rtl.dev.css, there are comments that suggest the line numbers of corresponding rules in wp-admin.dev.css . However, these comment lines are outdated.

The task is to update these line numbers, and re-order the rules as necessary based on the corresponding line numbers in wp-admin.dev.css.

Sections such as Media library, TinyMcE, ltr, no italic at the bottom of the files don't need updating.
