| Forced colors mode - transitions. |
| Tests that color transitions work in forced colors mode. |
| The only way to get transitions to work in forced colors mode is if |
| forced-color-adjust is none. Otherwise, the color will always be |
| overridden upon transition, and no transition will actually happen. |
