My colleague Chris Povirk discovered the following issue:

In the following example the two methods are given the same ID by javadoc of "m(E)":

```
$ cat JavadocSameSig.java
public interface JavadocSameSig {
  <E extends Object> void m(E e);
  <E extends Comparable<? super E>> void m(E e);
}

$ java -fullversion
openjdk full version "21+35"
$ javadoc JavadocSameSig.java
...

$ grep 'id="m(E)"' JavadocSameSig.html
<section class="detail" id="m(E)">
<section class="detail" id="m(E)">
```

So, if you click a link for `m(E)` in the method summary, it takes you to one of those, no matter where the link is "supposed" to go.

Plus, the method summary is actually showing only 1 method, rather than 2.

(With JDK11, I see two methods in the summary, though there's still the problem that the links can lead to only one of the methods' details.)
