Description
I found some code that was looping over a hashset, and removing items. Hashset is not throwing when you remove while enumerating like it used to.
It's convenient that it's like this, but it's different then how it used to work, and I'm not sure if it's safe.
The documentation says it should throw, so either the documentation needs to be updated, or the Hashset needs to be fixed.

Reproduction Steps
HashSet<int> set = new();
set.Add(1);
set.Add(2);
foreach (var x in set)
{
set.Remove(x);
}
Expected behavior
Throws an invalid operation exception
Actual behavior
It works
Regression?

Known Workarounds
Don't do it?
