I noticed a change in popup behavior when I upgraded ArcGIS API from v4.6 to v4.7. I have a layer with images in popup template. Some features in that layer may not have an image, i.e. {Image} field empty.
In JSAPI v4.6, the popup will not show image when empty, as expected:

However, in JSAPI v4.7, the popup will show an empty image, which looks very weird:

Here is an running example:

I'm wondering if this change is made on purpose or it's a bug in v4.7 API? Thanks.
