遮罩重绘出现问题。

### 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

lanpaint节点或是其他任何重绘的遮罩局部修改节点都出图变成色块。

### Actual Behavior

### Other

Reproduce the color-block output with the lanpaint node or another mask-local-editing node using the workflow shown in the issue. Start by checking the mask and output-shape information in the logs, then compare runs with custom nodes disabled; the fix is done when localized mask edits produce normal image output rather than solid color blocks.
