Using gr.update(value=np.array(...)) Disables Brush Painting in gr.ImageMask

[gkalstn000]

Describe the bug

When using the gr.ImageMask component in a Gradio interface, the brush painting functionality works as expected when an image is uploaded via the web interface. However, if the component is updated programmatically with gr.update(value=np.array(...)), the brush painting feature stops working entirely.

Reproduction

Steps to Reproduce:

1. Initialize the component:

canvas = gr.ImageMask(sources='upload', type="numpy")

Upload an image through the web interface.
Use the brush tool to paint on the canvas (this should work normally).

Update the component internally using:

image = gr.Image(sources='upload', type="numpy")
canvas = gr.ImageMask(sources='upload', type="numpy")

image.upload(fn=update_cnavas, inputs=image, outputs=canvas)

def update_cnavas(image) :
    return gr.update(value=image)

Observe that after the update, the brush painting functionality is completely disabled.
