1. Phorge at `2d997c3f107efe78707404e6e7787f9eb1df54f4`, PHP 8.2.14
2. Create task `T1`
3. In MariaDB, `UPDATE maniphest_task SET description = (UNHEX("606060642001335A2C606060")) WHERE id = 1;`
(**note:** `01` is not rendered by most browsers, see screenshot below)
4. Go to task `T1` in web browser
`EXCEPTION: (Exception) Matched token key "3Z" while processing remarkup block, but this token does not exist in the token map.`
