Error when drag off the end of the slider

[Shadercloud]

If you drag the handle off the end of the slider then mouse up you get error:

Uncaught TypeError: Cannot read properties of null (reading 'classList')
    at slider.js:1:37515

Nevermind, this was actually due to the slider being inside a modal, and when you dragged outside the modal it was causing the modal to close. (slider no longer existed in the DOM so error...)
