interval with large period keeps emitting

[cec]

Bug Report

Current Behavior
Passing a large period to interval(period: number, scheduler: Scheduler): Observable results in continuous emissions instead of 1 after given period passed.

Reproduction
Sadly I can't provide a StackBlitz due to corporate firewall issues, but I managed to reproduce the problem here using rxjs-playground.github.io.

I'm posting the same code here:

var largePeriod = 2240240746; // roughly 26 days in milliseconds
Rx.Observable.interval(largePeriod).subscribe(val => console.log(val))

Expected behavior
The Observable should not emit until given period has passed.

Environment

• Windows 10
• Runtime: Node 8.9.4, Chrome 71.0.3578.98
• RxJS version: 6.2.2

Additional info
I know that the such a large period is very awkward. I'm getting such a large value from a backend system telling me that the time-window for a given operation expires at some point in the future.

As a workaround I can pass to interval min(backendValue, largestPeriodNotExposingThisBug), but I believe it is right to inform you about this to prevent more problematic issues.

check #3015 , mostly same crux as we use javascript's timeout / interval.
