What happened?

When calling testcontainers.GenericContainer the passed ctx is ignored when reaching port forwarding logic at: https://github.com/testcontainers/testcontainers-go/blob/main/port_forwarding.go#L236 .

Relevant log output

No response

Additional information

I think a select against ctx.Done should be done in parallel to waiting on <-pfw.connectionCreated and should exit early returning ctx.Err(). If that sounds like an acceptable solution I could do a PR tomorrow.
