SQL Developer for VS Code

SELECT ‘[’ FROM DUAL;

Everything after the open [ shows in red. I've found one exception; an open double quote, ".

SELECT ‘[asdf"asdf’ FROM DUAL;

everything after the open [ is red, but from (and including) the double quote, ", the rest of the file is shown in orange.

There may be other combinations where highlighting hierarchy is broken as well, but I haven't come across them. Looks like “closing” the brackets and/or double-quotes “resolves” it for the highlighter, further underlying a hierarchy issue:

I'm on 25.4.1 for the extension and VSCode:
