Bug with advanced searches in regard to sorting order

I noticed a little bug with advanced searches. If you do a search with for example sorting by votes descending, IMDB usually generates an URL like following:
https://www.imdb.com/search/title/?title_type=tv_episode&sort=num_votes,desc
Since yesterday or so this will still give you the correct results, but the URL changes to
https://www.imdb.com/search/title/?title_type=tv_episode&sort=num_votes,asc
I.e. the "desc" changes to "asc". When you reload the page, the sorting will be reversed.

Edit: This happens on both browsers I've tried it on: Chrome and Safari.
