"This Tweet is unavailable." in not blocked account under the tweet?

Hello.

Here is a example: https://twitter.com/Tobias_Claren/status/1224787341887311872?s=20

But I still tweet reactions to their tweets. I copy the link to the tweet into my tweet.
As a result, a preview is displayed below the tweet.
