doens't tolerate a space before a block style indicator

[joachim-n]

It crashes on this:

- just: write some
- yaml: |
  some 
  block
  text

but not on this. with the space removed before the '|':

- just: write some
- yaml:|
  some 
  block
  text

The example on https://yaml-multiline.info/ has a space in it, so it looks like it should be allowed.

Your first example is probably not what you think it is. I think you rather meant:

- just: write some
- yaml: |
    some
    block
    text
