| // The `impl Foo` heading underneath `Implementations` has a ยง | 
 | // anchor to its left (used for linking to that heading). The anchor only shows | 
 | // up when hovering the `impl Foo`. This test ensures there's no gap between the | 
 | // anchor and the `impl Foo`. If there were a gap, this would cause an annoying | 
 | // problem: you hover `impl Foo` to see the anchor, then when you move your | 
 | // mouse to the left, the anchor disappears before you reach it. |
