gr.Image fullscreen button does not scale the image but scales the EventData

[Zarxrax]

Describe the bug

When I load an image into gr.Image which is smaller than my screen, and I press the fullscreen button, the image remains the same size and surrounded by black borders, rather than being enlarged to fill the screen. I would expect the fullscreen button to make the image larger, otherwise, what is the point?

However, I noticed that when in fullscreen mode, the EventData x/y coordinates DO get scaled as if the image is fullscreen, which breaks use cases where you need to obtain the clicked coordinates.

Reproduction

import gradio as gr

# Define a function to handle the image click event
def handle_click(image, event_data: gr.SelectData):
    # Extract the coordinates from the event data
    x, y = event_data.index
    # Return the coordinates as a string
    return f"Clicked at coordinates: ({x}, {y})"

# Create a Gradio Blocks app
with gr.Blocks() as demo:
    # Add an Image component for the user to upload an image
    image_input = gr.Image(label="Upload an Image")
    # Add a Textbox to display the coordinates
    coordinates_output = gr.Textbox(label="Coordinates")
    # Attach the click event to the image input
    image_input.select(handle_click, [image_input], coordinates_output)

# Launch the app
if __name__ == "__main__":
    demo.launch(show_error=True)

My understanding is that the image itself needs to be sufficiently large, otherwise blowing it up to be full screen will result in a low-res blurry image. cc @hannahblair for confirmation

This is a bug! We should fix
