Hello!
If you configure the hiding of fields based on linkage rules in the editing form, they disappear completely from view. In other words, they are not “marked” visually in any way.
There is a similar setting - only in block linkage rules - but there, hidden blocks are visually displayed in a transparent form.
That is, they can be seen (more precisely, their presence in the interface configuration), and this is very convenient, because I know that I have hidden elements. However, this feature does not work in the editing form for field conditions, which is inconvenient because I may forget that I have elements (fields) hidden by condition and add them again.
Or am I configuring something incorrectly?
