Description
Here's a description of what I'm observing:
1. Set up tables, add a few rows into the database.
2. Execute a select query using fulltext search: it returns 0 rows (which is incorrect, it should return 1).
3. Execute another select query (which is a modified version of (2))
4. Execute the same select query from (2): now it returns 2 rows (which is also incorrect, it should return 1).
Here's SQL script to reproduce (queries in question are 3 SELECTs at the bottom):

Locally I can reproduce this quickly with Docker. Save SQL above as "statements.sql" and then:
docker run -d -e MARIADB_ROOT_PASSWORD=test -e MARIADB_DATABASE=test -p 3306:3306 mariadb:latest |
mysql -u root -ptest --protocol=tcp test |
mysql> source statements.sql |
