`@mantine/styles` missing `@emotion/*` dependencies

What package has an issue

@mantine/core

Describe the bug

The actual problem seems to be in @mantine/styles but the selection dropdown doesn’t have that option.

In a project using yarn 3.2.4, I encounter the following problem when creating a custom styles cache:

This will happen even without getting any yarn installation errors. After some investigation, I believe this is because createEmotionCache is re-exported in @mantine/core from @emotion/cache, although the former isn’t re-exporting those type definitions nor listing the emotion library as a dependency.

I’m not sure of the intention behind these changes, but including @emotion/cache as a dependency of @mantine/styles fixes the issue.

What version of @mantine/hooks page do you have in package.json?

^5.6.3

After some thought I’ve decided to reopen this so we make sure it gets fixed when merging #2842 (or performing the corresponding Mantine update).
