I'm trying to write the same lua file than initial issue but the hover doesn't send the same response (param doesn't appear), but I have tested by writing jsdoc in a ts file:

/**
 * ```lua
 function f(a:aa) -> nil
 ```
 
 ___
 ```plaintext
 params: a
 ```
 ___
 
 */
function foo() {
}

foo()

And here the result:

I think we should keep the code blocks. That's how intellij shows code snippets

LSP4IJ's behavior is consistent with that.

Maybe @CppCXY's issue is the block's background seems darker on completion, compared to hover. Not sure what we can do about it.
