Prefix is printed if no hit with select(kind == ...)

Prefix is printed if no hit with select(kind == ...)
Following the example from https://mikefarah.gitbook.io/yq/recipes#export-as-environment-variables-script-or-any-custom-format I added a prefix to the output. Up to 4.45.2 all was fine but at least since 4.45.4 the prefix is printed if no match found

Version of yq: 4.45.4
Operating system: windows/....
Installed via: manually

Input Yaml
data1.yml:

# a: 1
# b: 2

# fruit:
#   - apple
#   - banana
#   - peach

Command
The command you ran:

yq '.. | (
  ( select(kind == "scalar" and parent | kind != "seq") |
      "scalar_" + key + "='\''" + . + "'\''" ),
  ( select(kind == "seq") |
      "seq_" + key + "=(" + (map("'\''" + . + "'\''") | join(",")) + ")")
)' data1.yml

Actual behavior

scalar_
seq_

Expected behavior

no output

Additional context
Uncomment scalars or sequence and all is fine.
