Description

This was introduced as part of #553, that added link margins in notification bars via d71eae8:

^^ adding the extra $spacing-sm there.

It is often seen at mozilla/sumo where links are at the end of sentences right before punctuation. This margin moves the interpunction weirdly around, making it feel like a bug (or at least from typography pov it's somewhat surprising to see this).

Steps to reproduce

https://protocol.mozilla.org/components/detail/notification-bar--error

Change the error text to include link inline within a sentence, e.g. from:

• "Error! Something has gone horribly wrong. Undo?"
  to
• "Error! Something has gone horribly wrong. You can undo the last action."

Expected result

Actual result

Environment

but looks bad if it's just a word:
