Collapsing of functions in the editor breaks if there is a comment before and after the function declaration

VSCode with sumneko.lua 3.7.4

Reproducer:

-- foo
function foo() -- foo
	if a then
		return a
	end
end

This code shows two collapsing/folding indicators to the left, one for the if (expected) and one for the comment (unexpected), but none for the function itself:

Clicking the first folding icon results in this:

It looks like it thinks the two comments belong to one comment block for the function instead of being unrelated comments.

首先，使用提供的 Lua 示例在 VSCode 中复现折叠行为，并比较注释、函数和 if 块周围的指示器。完成的标准是注释保持分离，函数获得预期的折叠指示器，同时不破坏 if 块的折叠行为。
