[Bataran]

Please answer these questions before submitting a bug report.

What version of OpenTelemetry are you using?

"@opentelemetry/api": "1.0.3",
"@opentelemetry/sdk-trace-base": "1.0.1"

What version of Node are you using?

v16.13.0.

Please provide the code you used to setup the OpenTelemetry SDK

// index.js
const opentelemetry = require('@opentelemetry/api');
const { BasicTracerProvider } = require('@opentelemetry/sdk-trace-base');

new BasicTracerProvider().register();

const span = opentelemetry.trace.getTracer('default').startSpan('foo');

span.setAttribute('key', 'value');
span.addEvent('some-event-1');
span.addEvent('some-event-2');
span.addEvent('some-event-3');
// the span has 1 event even though it's been run with OTEL_SPAN_EVENT_COUNT_LIMIT=0
span.end();

What did you do?

I started the script with OTEL_SPAN_EVENT_COUNT_LIMIT set to 0
env OTEL_SPAN_EVENT_COUNT_LIMIT=0 node index.js

What did you expect to see?

I expected to have no events in the span

What did you see instead?

There is one event ('some-event-3') in the span
