Description

Similarly to #4649 and #4774, comments are stripped after trait headers if after a generic parameter:

Before:

trait Foo<T> // my comment 
{}

After:

trait Foo<T> {}

Before:

trait Bar<T> /* My comment */ {
    fn bar();
}

After:

trait Bar<T> {
    fn bar();
}

Research direction

No file or test is named. Start by reproducing the examples for generic trait headers with line and block comments, then compare the behavior with issues #4649 and #4774. Done means rustfmt preserves comments between the generic parameter and the trait body.
