forkJoin/combineLatest works differently from 6.6.2 to 6.6.3 and even latest version 7.8.1

Describe the bug

forkJoin/combineLatest works differently from 6.6.2 to 6.6.3 when used with a ReplaySubject and Observable, the replay subject doesn't seem to emit the next value.

Expected behavior

From the reproduction URL provided below

Expected console output (as seen in rxjs <= 6.6.2):
0:one
1:two

Actual console output (as seen in rxjs >= 6.6.3):
0:one
0:two

I thought combineLatest might solve this issue instead, but even using combineLatest also doesn't make any difference

Additional context

I cant find anyone mentioning this problem from an internet search but as 7.8.1 is two years old it would strike me as odd that if this is a bug no one else has discovered it. So perhaps it's just a case of incorrect usage of the library?

Start with the linked StackBlitz reproduction and compare the console output under RxJS 6.6.2, 6.6.3, and 7.8.1 for forkJoin and combineLatest with ReplaySubject and Observable. Determine whether the changed output is a regression or expected usage, with the comparison and explanation serving as the completion criteria.
