HowTo:
1. When holding a key to show the status effects info, press PrintScreen or Alr+Tab out of the game.
2. Now the UI element stays persistent through all turns.
3. It can be canceled by pressing the key for showing this the second time.
Due to the alt+tab nature, it's possible this might not be happening the same on all oses.
Edit: Can also persist if the next turn is enemy's and the turn gets auto-ended while you're holding the status effect tooltip key.
