[5.x] Icon thumbnails in card view

I noticed a particular behavior with card thumbnails within a matrix field. If the first card you add has a thumbnail, the thumbnail will display. If the first card doesn't have a thumbnail (like this text entry type), any subsequent cards won't display a thumbnail whether they have one or not. I feel like this is a bug, but maybe it's the intended behavior?

@ryanleichty I’m not able to reproduce that. Are you positive those are the same entry type? (You can have multiple entry types with the same name).

What happens if you reload the page? Any change?

Here’s what I’m seeing:

@brandonkelly Sorry for the late response! I just tried this again and it was giving me the same issue, although a slightly different pattern. I'm not sure exactly why it sometimes shows a thumbnail and other times it doesn't.

Here's the field setup:

• Matrix field (productGallery)
  • Entry (row)
    • Matrix field (columns)
      • Entry type (image)
      • Entry type (text)

Ok, odd thing just happened, I deleted the top row in the screenshot above that has two image entries. Now the second row with the one image entry that previously showed a thumbnail now doesn't show a thumbnail. It seems like it's the first row that doesn't want to show any of it's child entry thumbnails.

I’m still unable to reproduce that. Can you try enabling safeMode to rule out any plugins/modules that could be interfering?
