New Markdown Javadoc formatter incorrectly merges code blocks into preceding line

[garretwilson]

I'm using Eclipse EE 2025-12 (4.38.0), which has support for formatting JEP 467 Markdown Javadoc comments. (This functionality is presumably for issue #4337 and pull request #4418, which is odd because that neither of those were closed. So where is the implementation tickets to file this bug against?)

Formatting a Markdown Javadoc comment with code block incorrectly joins the code blocks with previous lines. (See also the similar issues encountered with line splitting and block formatting in the old-style HTML Javadocs discussed in #991.)

Start with a comment like this:

/// To create rows for storage, use [Row#of] factories or [Row#builder()]:
/// ```java
/// Row row = Row.of(userId, "user123", age, 25);
/// tableDb.put(tableName, row).join();
/// ```

After formatting, that produces:

/// To create rows for storage, use [Row#of] factories or [Row#builder()]: ```java Row row = Row.of(userId, "user123", age, 25); tableDb.put(tableName,
/// row).join(); ```

That is broken. I'll have to turn off Markdown formatting altogether for now. (Maybe that's why #4337 was never closed—it was never implemented?)

This is handled in #4418 👍
