YAML synatx in md

[brokuka]

Let's say we have some data like this:

::gear2
---
id: imperial-boots
name: Imperial Boots
slot: boots
rarity: epic
statsProgression:
  heroDefense:
    values:
      - 40
      - 50
      - 60
      - 80
      - 100
      - 120
      - 140
      - 160
      - 179
    extra:
      '100': '100'

---

in all yaml to js online service it will transfers as expect, but in md files

'100': '100' make array of index 100, how to prevent that? Need to make object instead of array.
