Macros in keys do not get resolved in UI

Steps to reproduce:

1. Use a macro in a normal item key (not a discovery item)
2. List items of template/host

Result:
See screenshot...

Expected:
The macro is resolved for the item name so I expected it to be resolved for the item key the same way.

and how it looks when listed in a host/template item view:

the {$SEARCHPATTERN} resolves to `tomcat` for Name but not for the `Key`
