Is this addon compatible with IE11?

After installation and configuration, when I run storybook and open on IE11 it shows some errors:

SCRIPT5007: Unable to get property 'classList' of undefined or null reference

The above error occurred in the <ThemeStory> component: in ThemeStory (created by ThemeSelector) in ThemeSelector (created by render) in render in Unknown in div (created by Context.Consumer) in Side (created by FlexBar) in div (created by Context.Consumer) in Styled(div) (created by FlexBar) in div (created by OverlayScrollbarsComponent) in div (created by OverlayScrollbarsComponent) in div (created by OverlayScrollbarsComponent) in div (created by OverlayScrollbarsComponent) in OverlayScrollbarsComponent (created by Scroller) in Suspense (created by Scroller) in Scroller (created by Context.Consumer) in Styled(Scroller) in Unknown (created by Context.Consumer) in Bar (created by FlexBar) in FlexBar (created by Bar) in Bar (created by Context.Consumer) in Styled(Bar) in Unknown (created by Context.Consumer) in Location (created by QueryLocation) in QueryLocation in Unknown in ZoomProvider in Unknown

The above error occurred in the <LocationProvider> component: in LocationProvider (created by Root) in HelmetProvider (created by Root) in Root

SCRIPT445: Object doesn't support this action

SCRIPT5007: Unable to get property 'getOwnPropertyDescriptor' of undefined or null reference

I only want to know if this addon is tested on IE11 to continue integrated it on my storybook.

Thanks in advance.
