Vase Mob Blocks Path in Trial

On the fourth floor of the Trial of Sekhemas, I did an Hourglass trial and encountered some vase-looking like mobs which move when active but become stationary obstacles when inactive. After completing the trial, I couldn't move into the room with the rewards because one of the vase mobs blocked the door. While it was active it stood in front of the door and when I completed the trial, it remained stationary right in front of the door, blocking the path.

The only way to continue is to leave the trials and go back in but I lost my reward (restored honor and a boon).
