System information

go install github.com/nektos/act@latest

Expected behaviour

As on GItHub I expect it to echo:

{
  "v1var": "v1",
  "v2var": "v2"
}

Actual behaviour

It prints:

{
   "v1var": "",
   "v2var": "v2"
}

To be honest this feature sounds like a race condition out of the box; it's unclear how to interpret the results when one matrix stream is delayed or failed. Can you check if this PR produces somewhat expected results? https://github.com/nektos/act/pull/5993
