[Bug]: `Reverse progress bar direction` under `Progress Effects` doesn't change the `Both Ends` effect

Description of the bug

Reverse progress bar direction under Progress Effects doesn't change the Both Ends effect.

I'm not sure if this is the intended behavior but I expected the progress to "grow" from the center rather than the end when I selected Reverse progress bar direction

No response
