'uui-ref' spacing is different when readonly is enabled

[lauraneto]

Which exact UI Library version are you using? For example: 1.0.1 - don't just write v1.

1.12.2

Bug summary

When toggling readonly for references (uui-ref-*), the spacing changes. I would not expect this to change.

In my case I was trying to replicate the content history tab in my own dashboard, and it can have a mix of readonly and non readonly entries. At the moment there is a difference in alignment between both types of entries.

Specifics

Steps to reproduce

1. Open a Reference component in storybook (example: https://uui.umbraco.com/?path=/docs/uui-ref-node--docs)
2. Switch readonly between true and false to see the spacing changing.

Expected result / actual result

No visual changes (unless interacted with, or other expected readonly behavior).
