[Bug]: ControlNet not working with Inpaint in "Inpaint not masked" mode

Nobody has claimed this yet.

### Checklist

- [X] The issue exists after disabling all extensions
- [X] The issue exists on a clean installation of webui
- [ ] The issue is caused by an extension, but I believe it is caused by a bug in the webui
- [X] The issue exists in the current version of the webui
- [ ] The issue has not been reported before recently
- [X] The issue has been reported before but has not been fixed yet

### What happened?

When using "Mask mode: Inpaint not masked", ControlNet does not work. This is inconsistent with the ControlNet implementation in Automatic1111/stable-diffusion-webui.

This issue is closely related to #76, which was fixed last month.

### Steps to reproduce the problem

1. Go to img2img/Inpaint
2. Type a simple prompt and drop a picture onto the canvas
3. Set Mask mode to "Inpaint not masked"
4. Set Denoising Strength to 1
5. Set ControlNet Unit 0 to Enable, Tile, tile_resample, control_v11f1e_sd15_tile, Control Weight 0.5
6. Generate an image. Notice that the generated image has no ControlNet Tile processing applied to it. The generated image looks exactly the same as when ControlNet is disabled. Also notice that the ControlNet input preview is a completely black image.

Two more observations:
1. When enabling "Upload independent control image" and using the same image, ControlNet works as expected.
2. Switching the Mask mode to "Inpaint masked" and drawing a mask that covers the entire image works as expected. Again, the expectation is that "Inpaint not masked" with no mask is analogous to "Inpaint masked" with a full mask, and should result in the same behavior. This is how ControlNet works in stable-diffusion-webui.

### What should have happened?

"Inpaint not masked" with no mask should behave the same as "Inpaint masked" with a full mask

### What browsers do you use to access the UI ?

Mozilla Firefox, Google Chrome

### Additional information

_No response_

Start by reproducing the listed img2img/Inpaint steps with ControlNet Unit 0 configured for Tile, then compare the ControlNet inpaint handling with Automatic1111/stable-diffusion-webui. Done means “Inpaint not masked” with no mask produces the same ControlNet behavior as “Inpaint masked” with a full-image mask, including a non-black input preview.
