V4: ion-icon doesnt appear in certain situations

I’m trying to wrap <ion-icon> inside <ion-thumbnail> and nothing appears.

I put together a stackblitz–but there I can’t get any kind of icon to show. what am I missing?

Does your icon shows up, if it’s outside of the thumbnail block??

in my app it does. in the Stackblitz it does not.

Then maybe some problem persists with Stackblitz you may try some other.

well thats a dumb response. My problem still persists: <ion-icon> inside <ion-thumbnail> and nothing appears. Stackblitz has nothing to do with it.
