Comment (by desrosj):

 Thanks @Otto42! [attachment:"48517.2.diff"] just runs the related RTL
 build tasks in Twenty Nineteen and Twenty Twenty to ensure the headers are
 fixed in the `-rtl` stylesheets. They are not read, but the files are
 direct copies with RTL transformations, so good to keep them in sync.

 For Twenty Twenty, I also
 [https://github.com/WordPress/twentytwenty/pull/969 opened a PR] to make
 the changes up stream. While development there will soon die down, I think
 it's good to sync that over just in case a few changes are copied back
 over to SVN before official release.
