This was working with 1.16.1 version of a plugin. Possible regression?

Here is agent configuration that used to work:

agent {
 kubernetes {
   label "${pipelineParams.argoApplicationPrefix}-preflight"
   defaultContainer 'jnlp'
   idleMinutes 1
   inheritFrom "maven mysql-57 kaniko"
 }

After upgrading to to 1.20.0 resulting pod template only what was in last entry in that list.

Documentation is lacking on how one can change `yamlMergeStrategy` in declarative pipeline, but I tried creating the same pod temple in Global Configuration with `merge` as strategy - no luck.
