Deactivating Pjax and Smooth does not remove css rules

Hello,
When enabling Pjax and smooth scroll, Bricks Forge adds a style attribute on the HTML : style=“scroll-behavior: smooth;”. Deactivating the feature does not remove the attribute.
It’s worse with Pjax with style="opacity: 0 and style="opacity: 1 still being applied to the body causing a white flash on page load, especially visible with Firefox for some reason.

The only way to get rid of it is to deactivate the plugin.

I hope my explanations aren’t to confusing.
Let me know if you need more information.
Thanks !

PS : i ruled out caching.
