OpentelemetryOban.JobHandler - Trace - Parent Span being ignored

[linqueta]

Describe the bug
I have a piece of code where I have an OpenTelemetry Trace Span already in context, and I set them in the field meta to the following Oban Jobs. Once the Oban Jobs starts to process, it triggers OpentelemetryOban.JobHandler.handle_job_start/4, but it's ignoring a possible parent span, ignoring the three entirely (OpenTelemetry.Tracer.set_current_span(:undefined))

A simple change to OpenTelemetry.Tracer.set_current_span(parent) makes it work, having a parent or not.

Expected behavior
Respect the parent span passed into job_meta, calling to OpenTelemetry.Tracer.set_current_span(parent)

Additional context
Add any other context about the problem here.

Is it setting it to a Link? The active span that creates the job should be linked to and is not considered a parent. Though I'd have to verify if its not in the semconv that it could be optionally set as parent and not a Link.
