z-index on floating ui components seems to be failing

[aaronstezycki]

Hi I've created a few re-usable components with floating parts, i.e the select, and popovers. Strangely I've used these components a few times and had no problems with z-index, but on this one svelte kit app, all the elements get rendered with z-index: auto instead of applying correct z-index of '7000' or an index higher that the parent.

Can anyone advise how the components automatically apply z-index when using floating content wrappers? There something I'm missing?
