IntelliJ IDEA can't recognize method recursion in a forEach call

Consider the following code I attached as an image:

enter image description here

The code does an infinite loop but that's not the point. The point is that if I make the recursion inside a for loop then IDEA can show that at the left with a sign.

If I make the recursion inside a forEach lambda expression then there are no sign.

It would be much comfortable if it can be shown in both cases. Is it a bug, or is there any reason for that?

As correctly noted by @Jesper in his comment, not every lambda is called synchronously from the function to which it is passed as a parameter. Imagine that the function used in the example was invokeLater and not forEach.

Since IntelliJ is not aware of the semantics of specific library functions that take lambdas as parameters, it does not highlight recursive calls in any lambdas.
