Bulk generate ignores new feed settings

To reproduce, create some vocabularies and terms in taxonomy. Then enable Pathauto and go to Pathauto settings. Leave everything as defaults, but go to "Taxonomy term path settings" and expand it. Blank out the "Internal feed alias text" field to disable this feature, check "Bulk generate" and save. It will create paths for all your terms, but if you visit a term the RSS feed URL will be default (expected, we disabled it).

Now back in Pathauto settings put something in the "Internal feed alias text" field (I just put the word "feed" back). Check "Bulk generate" and save. Nothing! It doesn't bulk generate the feed aliases. It ignores them.
