Description

When scrolling upwards the javascript removes the top: 131px element style of the button.

This breaks the positioning when activating navigation.tabs.sticky as the button is partially hidden behind the navigation tabs.

Expected behaviour

The element style for top: on the back-to-top button should not be removed when scrolling upwards.

Actual behaviour
