Description

Deprecate categories are still visible in Category selection tabs. For example in the ElementDefinition and ElementUsage dialog editors. They should at least be colored differently and filtered out based on the deprecated view setting. Next to that keep the following related issue in mind: #1315

It might be that the same issue exists for other multi select lists.

@samatstariongroup Solution for now is to show the items as deprecated (gray background), but no filtering out yet.
