Generated documentation for single line enum duplicates the same documentation for each enumeration

[dhoverml]

Godot version

v4.2.master.custom_build [98b50eb]

System information

Ubuntu 20.04 LTS

Issue description

Reproducible on 4.2dev3, 4.2dev4, and master.
This is not reproducible on 4.1.1-stable and 4.2dev1 (4.2dev2 crashed).

By single line enum I mean:

## My documentation
enum MyEnum { A, B, C }

The generated documentation looks like this:

The generated documentation for an enum formatted like this

## My documentation
enum MyEnum {
  A,
  B,
  C
}

looks correct

Steps to reproduce

1. Attach a script to a node
2. Add this:

## My documentation
enum MyEnum { A, B, C }

3. Open the documentation for that node

Thanks for the ping! Also @dalexeev who's done a lot of wonderful fixes to the docgen lately, and might have a little more time :) But it's on my radar!

Thanks, I know that this bug exists and I know where it is caused. I wanted to take a look at this along with #78934 when I have time. This is a parser issue, not a DocGen issue.

godot/modules/gdscript/gdscript_parser.cpp

Lines 783 to 798 in 3ed4497

	class_doc_line = MIN(class_doc_line, doc_comment_line - 1);
	// Check whether current line has a doc comment
	if (has_comment(previous.start_line, true)) {
	if constexpr (std::is_same_v<T, ClassNode>) {
	member->doc_data = parse_class_doc_comment(previous.start_line, true, true);
	} else {
	member->doc_data = parse_doc_comment(previous.start_line, true);
	}
	} else if (has_comment(doc_comment_line, true)) {
	if constexpr (std::is_same_v<T, ClassNode>) {
	member->doc_data = parse_class_doc_comment(doc_comment_line, true);
	} else {
	member->doc_data = parse_doc_comment(doc_comment_line);
	}
	}

Since you already know where/what, I'll stay away from this one! :)
