Ensure all plugins are executed for a given candidate (#6540)

* remove early return so that all plugins are handled

We had an early return so that once a plugin was matched, that we could
stop running the code through the other plugins. However, in this case
we have an issue that user defined css is technically also a plugin.

This means that:
  - `bg-green-light`
Would check for:
  - `bg-green-light` (no hit, continue)
  - `bg-green` (Hit! Don't execute next plugins)
  - `bg` (This is the one that would have generated `bg-green-light`)

We tested this change and it doesn't seem to have an impact functionally
and also not really performance wise.
