An empty icon value at {key} renders nothing; omit `icon` instead.

What happened

An icon slot was given the empty string. That is not the same as omitting the icon - it says "there is an icon here" and then draws nothing - so the slot renders empty and the difference is named. null and undefined are the supported way to say there is no icon and are not reported.

The fix

Omit the icon property, or give it null, when there is no icon.
