fix(lib): global styles get re-enabled when useFieldPlugin is called multiple times

[johannes-lindgren]

What?

useFieldPlugin calls createFieldPlugin, which disabled the global styles as a side effect. It also attempts to clean up the side effect by enabling the style sheet again. This means that when a component that calls useFieldPlugin unmounts, the cleanup function enables the style sheet again. But this causes an issue if there is still another component that was using this side effect:

1. Component A is rendered, and calls useFieldPlugin. The style sheet gets disabled.
2. Component B is rendered, and calls useFieldPlugin. The style sheet remains disabled.
3. Component B unmounts, so the cleanup function runs. The style sheet is re-enabled.
4. Component A is still mounted, but the style sheet is now enabled.

Originally, createFieldPlugin was not meant to be called more than once: you were supposed to pass the state and methods via context or props.

As a solution, I think we can simply skip removing the disabled attribute from the style element,

How to test? (optional)

Hey @Dawntraoz 🙌

Q: Syncing this change with the field-plugin moved to the monorepo is something feasible, or should the changes that happen here be manually replicated there? 🤔

Probably yes, but as I haven't done it before, I'm curious about it.

It is feasible, indeed, no need for manual changes, these changes will be rebased on the monorepo for now, using a CLI tool I created to handle git subtree folders 🙏 Once I do it, I can show you the process (that will not be needed once we have everything migrated there)
