Beta nodes "Cond Pair Set Props" and "Cond Pair Set Props Combine" seem to interpret mask as if they were inverted

### Custom Node Testing

- [x] I have tried disabling custom nodes and the issue persists (see [how to disable custom nodes](https://docs.comfy.org/troubleshooting/custom-node-issues#step-1%3A-test-with-all-custom-nodes-disabled) if you need help)

### Expected Behavior

Using "Cond Pair Set Props" and "Cond Pair Set Props Combine" nodes, I would expect the "mask" property on both to use high mask values to define the affected area, as usual.

### Actual Behavior

"Cond Pair Set Props" and "Cond Pair Set Props Combine" seem to use their masks values in a inverted way, affecting everything except the masked area.

Workaround is invert each mask

### Steps to Reproduce

Use "Cond Pair Set Props" and "Cond Pair Set Props Combine" with complementary masks.
Use "Create Hook Lora" as input to "Cond Pair Set Props" - use a LoRA with obvious effects, put at high strength.

### Debug Logs

```powershell
Don't have them on hand.

Sorry for not dropping a workflow, I thought you'd want to know this happens.
