Temporary workaround

patch_webdriverelement can be disabled by overriding fixture

from pytest_splinter.webdriver_patches import patch_webdriver

@pytest.fixture(scope="session")
def browser_patches():
    patch_webdriver()

@kalekseev thank you for both the problem report and the initial patch idea, as it saved my life. Looks like it is no longer relevant - closing it. Thanks!
