Describe the bug

I can expand case blocks within a switch statement, but cannot expand case blocks within a select statement.

Example of collapsing a case within a switch statement:

Example of where this isn't enabled for a case within a select statement:

Note: I can collapse the entire select statement, but that's not always the desired behavior.

While I cannot recall if this ever worked, this seems like odd behavior.
