Describe the bug

Version of yq: 4.35.2
Operating system: linux
Installed via: compiled from latest source

Input Yaml
data.yml:

- a: a1
  b: b1
- a: a2
  b: b2

Command

yq '.[] | (.a , .b)' data.yml

Actual behavior

a1
a2
b1
b2

Note that jq works like the expected behavior.

workaround:

yq '.[] | [.a ,.b] | .[]' /tmp/test.yaml
