Selenium: Capability['ignoreZoomSetting'] doesn't work on IE11 with py-selenium 3.8.1

Meta -

OS: Windows10

Selenium Version: 3.8.1

Browser: IE11
When I try to run python-selenium on IE11, I got an exception below

selenium.common.exceptions.SessionNotCreatedException: Message: Unexpected error launching Internet Explorer. Browser zoom level was set to 150%. It should be set to 100%

I have set IE capabilities like below

def ie_driver(self):
        ie_driver = r'C:\Users\ZiYingSu\Documents\python\IEDriverServer.exe'
        os.environ['webdriver.ie.driver'] = ie_driver
        cap = DesiredCapabilities.INTERNETEXPLORER
        cap['platform'] = 'WINDOWS'
        cap['browserName'] = 'internet explorer'
        cap['ignoreProtectedModeSettings'] = True
        **cap['ignoreZoomSetting'] = True**
        cap['IntroduceInstabilityByIgnoringProtectedModeSettings'] = True
        cap['requireWindowFocus'] = True
        cap['INTRODUCE_FLAKINESS_BY_IGNORING_SECURITY_DOMAINS'] = True
        self.driver = webdriver.Ie(ie_driver ,capabilities=cap)
        return self.driver

I don't get it why this capability['ignoreZoomSetting'] doesn't work ? I don't want to adjust my IE by manually everytime
Thanks

Browser Version: IE11(64-bit)

Expected Behavior -

IE can ignore zoom setting

Actual Behavior -

Got exception on selenium

selenium.common.exceptions.SessionNotCreatedException: Message: Unexpected error launching Internet Explorer. Browser zoom level was set to 150%. It should be set to 100%

It doesn't look to me like you are putting the option in the correct spot. That is an IE option, and needs to be in the se:ieOptions key within capabilities. I don't see how any of those options are taking without being in the right spot.

Try this code instead:

from selenium.webdriver.ie.options import Options

def ie_driver(self):
    ie_driver = r'C:\Users\ZiYingSu\Documents\python\IEDriverServer.exe'
    opts = Options()
    opts.ignore_protected_mode_settings = True
    opts.ignore_zoom_level = True
    opts.require_window_focus = True
    self.driver = webdriver.Ie(ie_driver, ie_options=opts)
    return self.driver
