Describe the bug
A clear and concise description of what the bug is.

To Reproduce
Steps to reproduce the behavior:

1. Declare a template doccomment on a method in an extension
2. Use elsewhere
3. Hover over method

```dart
class Foo {
  /// {@macro baz}
  ///
  /// {@macro pink}
  ///
  ///
  ///
  ///
  ///
  ///
  ///
  void bar() {}
  /// {@template pink}
  /// this works
  /// {@endtemplate}
  void pink() {}
}
extension on Foo {
  /// {@template baz}
  /// This does not work
  /// {@endtemplate}
  void baz() {}
}

Expected behavior
See the referenced template.
The template is shown if running dart doc, so this isn't an issue there.

Screenshots

As you can see, the baz template isn't rendered in the hover.
