firefox --headless selenium возвращает ошибку ElementClickInterceptedException

Запускаю тесты на двух браузерах: Chrome и Firefox. На Chrome --headless работает корректно.

Firefox --headless возвращает ошибку. Причем без --headless все работает отлично:

def get_firefox_options():
    options = firefox_options()
    options.add_argument('--start-maximized')
    return options

Пробовала устанавливать размер окна, но ошибка оставалась:

def get_firefox_options():
    options = firefox_options()
    options.add_argument('--window-size=1920,1080')
    options.add_argument('--start-maximized')
    options.add_argument('--headless')
    return options
