As far as I know, Twitter has always done this since the "Likes" were introduced. I don't think they're recorded in a permanent manner on who liked what, just the total number of likes per post as a counter.
Surprisingly it does show these posts on your "Likes" page in your profile. But they aren't marked as liked, and liking one will increase the like indicator.
Maybe through the app, but I get sent links to x things all the time and they just straight up don't load. Same thing with links to old x threads linked from different websites.
