Describe your issue

I declared a text style called subheader. Since passing nested keys is limited, I declared the additional uppercase separately in a weaker utility as a 'new' class. In the end, these get merged because they share the same name, so it's pointless for IntelliSense to show a duplicate hint.

Extra

I know that the strange duplication is caused by the fact that I redeclare a separate utility named .text-subheader on top of the .text-subheader declared in @theme; this can also be seen in the playground hint.

Still, it doesn't make sense to show two identical suggestions, even if they're coming from two different sources.
