"Use coalesce expression" loses comments between variable declaration and if statement

[jhinder]

Follow-up to #82037, which I can't reopen for some reason.

Version Used: Local build of latest main revision, da6cf36, i.e. already containing the fix #82041.

Steps to Reproduce:
Invoke "Use coalesce expression" on the if statement.

class D
{
    public void M()
    {
        var value = M2();
        // Test
        if (value == null)
        {
            throw new InvalidOperationException();
        }
    }

    string? M2() => null;
}

Expected Behavior: The comment is placed before or after the rewritten statement.

Actual Behavior: The comment is dropped.
