Breadcrumb : Sentry events create breadcrumb with parameter sentry = false #2357

• [ x] @sentry/browser

Description

Sentry creates a breadcrumb when fetching the sentry.io server

My config uses parameter sentry: false.:
integrations: [
new Integrations.Breadcrumbs({
console: false,
dom: true,
fetch: true,
history: true,
sentry: false,
xhr: true
}),

From my understanding, it should not create this event with this parameter. In fact we dont need to know that sentry send an event to sentry as if we see it in Sentry that means we received it...

Reproduce code

Just do a captureException("test");

Then a breadcrumbs is created:
{
timestamp: 1576236352.789
category: "sentry"
event_id: "35d9016e9b4c43db9511a75bef9124eb"
level: "error"
message: "test: -s-"
}

Workaround

We can filter it with beforeBreadcrumb

Have a nice day,
