Target of tap operator triggers undefined variable highlight

[PikalaxALT]

ex.

ch_samplesheet
  .filter { meta, _fastq -> meta.single_read }
  .tap { ch_sr_samples }
  .collect { _meta, fastq -> fastq }
  .set { ch_sr_fastq }

Symbol ch_sr_samples in line 4 is marked as not defined, and also in subsequent references. To silence the error, define the affected channel before the operator chain including the tap.
