label not triggering form control elements events

In html, some events on form control elements can be triggered by interacting with the label itself, while in blitz they do not trigger them.
### Examples
```html
Label 1
Label 2
```

```rust
rsx! {
label {
onclick: move |_| {dbg!("label 1");},
"Label 1",
input {
onclick: move |_| {dbg!("input 1");}
}
}
label {
for: "input",
onclick: move |_| {dbg!("label 2");},
"Label 2"
}
input {
id: "input",
onclick: move |_| {dbg!("input 2");}
}
}
```

Start with the HTML and RSX reproductions in the issue, then trace Blitz's event dispatch for label elements and associated or nested form controls. Verify both examples, including click handlers on the label and input, and consider the work done when their behavior matches the browser examples.
