Follow-up on #52807

What?

This PR fixes a problem with the title being converted to the unintended string [object object] when the navigation menu is duplicated.

navigation_duplicate

Why?

The navigation object passed to the copy handler is obtained via useEntityRecord().

const { record: navigationMenu, isResolving } = useEntityRecord(
'postType',
postType,
postId
);

I don't fully understand, but the title property should be an object with raw and rendered properties, not a string.

How?

Reverted to the previous implementation of checking the rendered property.

Testing Instructions

  • Copy navigation.
  • The title of the copied navigation should be {Navigation Name} (copy).

Thank you for this fix 🙇

I tested this and

  • verified the original problem on trunk
  • verified this PR fixes that problem

What I'd like to understand (maybe from @jeryj) is why this happens? I thought we'd resolved all of this missing sub properties stuff previously?

I understand as follows.

  • The value of the title property of data retrieved by useEntityRecord(s) or getEntityRecord(s) is always an object with raw and rendered sub-properties
  • The value of the title property of data retrieved by getEditedEntityRecord is always a string.

In other words, of the areas refactored in #52807, the direct use of the value of the title property should be limited to those that internally depend on getEditedEntityRecord.

I have looked again at why this difference occurs, and this series of comments seems to be right on target.

Edited records use title: string instead of title: { raw: string, rendered: string; } so that's another special case to handle

Are you talking about the fact that we might store a string in the app but the API response has a different version of the data? If that's the case we may find that we have a different type for the API response and the internal data. That's a good thing though! By the way we can handle these cases through type utilities if the case is general enough and warranted.

Ah, I meant a quirk of how core-data treats certain properties. For example, posts retrieved using getEntityRecord have a title as an object with raw and rendered properties with raw block markup, and its rendered version respectively. If you start editing the data, though, and use getEditedEntityRecord, the title becomes a string containing the edits. These special properties are listed in rawAttributes in entities.js
