How could single content files and content folders with index be sorted correctly by weight?

[abovewave]

here is a example diagram of my hugo site:
.
├── content/
│ └── posts/
｜ ├── a/
｜ ｜ ├──_index.md
｜ ｜ ├──1.md
｜ ｜ └──2.md
｜ ├── b/
｜ ｜ ├──_index.md
｜ ｜ ├──3.md
｜ ｜ └──4.md
｜ ├── 5.md
｜ └── 6.md

I set weight at the front matter of every markdown file in this order:

a/_index > 1 > 2 > b/index > 3 > 4 > 5 >6

For the page www.example.com/posts, I am expacting that the listing would be in order

• a
• b
• 5
• 6

but what the site give me is:

• 5
• 6
• a
• b

Is there any way that the listing would be in the order I want? How could we weight across single content page and content folder page?
