12.5: search entry in context menu should be available in preview mode

Use case or problem

The preview mode doesn’t have the same context menu as edit mode, which was sensible since no editing can be done there and only copying of a word was really useful.

Proposed solution

But now that the new search option is available (which is great!), it would be sensible to add the context menu in preview mode as well. Because now, we may want to search instead copy.

Ideally, the context menu would be available without selecting a word, like in edit mode.
