[🐛 Bug]: Pasting images while headless prevent site from loading it.

[PaulStSmith]

Description

When running Selenium in headless mode, attempting to paste an image (e.g., via clipboard or send_keys) into a web application results in the image not being loaded or processed correctly by the site. The same operation works as expected in non-headless (headed) mode.

Reproducible Code

def send_image_to_clipboard(image_path):
    """
    Copies an image to the Windows clipboard.

    Args:
        image_path (str): Path to the image file to be copied.
    """
    image = Image.open(image_path)
    output = BytesIO()
    image.convert("RGB").save(output, "BMP")
    data = output.getvalue()[14:]
    output.close()

    win32clipboard.OpenClipboard()
    win32clipboard.EmptyClipboard()
    win32clipboard.SetClipboardData(win32clipboard.CF_DIB, data)
    win32clipboard.CloseClipboard()
    time.sleep(1)

send_image_to_clipboard("path/to/image.png")
editor = driver.find_elements(By.CSS_SELECTOR, "div[contenteditable='true']")
editor.send_keys(Keys.Control 'v')

Hi, @PaulStSmith.
This issue has been determined to require fixes in ChromeDriver.

You can see if the feature is passing in the Web Platform Tests.

If it is something new, please create an issue with the ChromeDriver team.
Feel free to comment the issues that you raise back in this issue. Thank you.

editor.send_keys(Keys.Control 'v')

Sending control keys in Chromium browsers requires a display, so it won't work in headless mode. This is a limitation of ChromeDriver and not something we can fix in Selenium.
