traceparent in meta tag not used

[drecaise]

Please answer these questions before submitting a bug report.

What version of OpenTelemetry are you using?

v0.16.0 (with document-load v0.13.0) and v0.14.0
Open

What version of Node are you using?

v14.15.4

Please provide the code you used to setup the OpenTelemetry SDK

opentelemetry-js/examples/tracer-web/examples/document-load

What did you do?

For the v0.14.0 test:

1. Clone repository
2. Navigate to opentelementry-js/examples/tracer-web
3. git checkout v0.14.0
4. Execute npm install
5. Execute npm start

I also tried checking out v0.16.0 and manually changing the document-load plugin to v0.13.0 in the package.json (Which gave the same result)

If possible, provide a recipe for reproducing the error.
Open up Chrome (In my case Chrome 88.0.4324.146 ) and navigate to: http://localhost:8090/document-load/

What did you expect to see?

I expected a trace for the load of the page with the same traceid as given in the meta tag of the index.html example:
ab42124a3c573678d4d8b21ba52df3bf

What did you see instead?

Only other traceids

Additional context

If I understand the explanation under: "Optional: Send a trace parent from your server" in this readme: https://github.com/open-telemetry/opentelemetry-js-contrib/blob/v0.13.0/plugins/web/opentelemetry-plugin-document-load/README.md correctly I should be able to create a single trace with server and browser part combined. For this, I assume, the generated trace from the browser should use the traceid from the traceparent meta tag.

Add any other context about the problem here.

Confirmed, I've successfully tested this:
Clone repository
Navigate to opentelementry-js/examples/tracer-web
git checkout v0.14.0
Edit package.json: Change plugin-document-load and plugin-user-interaction on lines 44-45 to use version "^0.13.0" instead of "^0.12.0"
Execute npm install
Execute npm start
Open up Chrome and navigate to: http://localhost:8090/document-load/ with the console open
Observed traceId is the same as in html meta tag

Thanks for quick clarification!
