Incomplete Stacktraces on test failures

[a-hat]

Hi everyone,
we are using gauge+taiko for E2E testing. I am currently wondering if it is possible to improve the output when a test fails. Most of the time, I do not see the corresponding line number in the test implementation where an exception occurs. This is probably due to the async handling.
Here is an example of an output from https://github.com/getgauge-examples/js-taiko

# API

As you can see, only the specification which failed is mentioned in the stacktrace, not the actual test implementation. I would expect to see a trace to this: https://github.com/getgauge-examples/js-taiko/blob/efab8b9703a834afff913308dd35496562360f5e/tests/step_implementation.js#L110

As this makes debugging tests much more difficult, any support on this would be highly appreciated.

Note that this is a possible duplicate to #184, but because this issue is over a year old I decided to raise a new one.
