I think there’s a bit of a problem with the “Slider” component from component store currently
Do you still see this problem? I tried reproducing it here on Safari but couldn’t… I know this happens, for example, when the styles are deactivated on the browser. Could this be the case?
How to deactivate styles or reactivate them on the browser?
On Safari: Safari > Preferences… > Show Develop menu in menu bar. Then go to the Develop dropdown and select the “Disable Styles” option.
