`prettier-ignore` in YAML seems to apply to all following nodes instead of just the immediate next node

Prettier 2.6.2
Playground link

# Options (if any):
--prose-wrap always

(happens regardless of --prose-wrap setting, but it's easier to see with it set to always)

Input:

# prettier-ignore
x:
  1
  2
  3
y: 
  1
  2
  3

Output:

# prettier-ignore
x:
  1
  2
  3
y: 
  1
  2
  3

Expected behavior:

# prettier-ignore
x:
  1
  2
  3
y: 1 2 3

Personally I think the expected behaviour makes more sense, but it could be the current behaviour is intended in which case I think the documentation could make it more obvious.

Currently it says:

# prettier-ignore should be placed on the line immediately above the ignored node:

which to me implies it'll only affect that node, rather than the nodes after it.

Reproduce the YAML case in the linked Prettier Playground and compare the current output with the expected output. Verify whether prettier-ignore should affect only the immediate next node; done means the behavior is corrected or the documentation clearly explains the intended scope.
