Where the fork did my purple dotted outline go on my assets?

So Assets have always had an auto applied purple dotted line and it is now gone on all of my assets that do not have variants.

How do I get it back? I rely on it as a visual cue so I can mentally/visually separate assets and design direction pieces (or random artifacts that I am working on).

Why would it just disappear? Did Figma really just remove it or is it something I did?
Thanks in advance.
