Different prompts are created with the same seed/variation seed in batch

[Velour-Fog]

Describe the bug
Different prompts are being chosen with the same main seed, and a different variation seed during batch creation.

To Reproduce
prompt: {red|blue} flower
batch count 2
seed: 1
variation seed: -1, variation strength: 0.1
with the above settings, 2 images are produced: "red flower" and "blue flower"

Are you using a local install or a colab?

Expected behaviour
With the same main seed and a different variation seed, it should produce the same prompt.

Additional context
In non-batch image generation prompt "{red|blue} flower" with seed 1, and variation seed -1 (strength: 0.1), will always poduce a "blue flower" (with slight visual variation). Setting the batch size to 2(or more) should function exactly as if you had not used batch, and just hit generate 2 times.
