This safe method is the basic block to access element attributes from layout.
We reuse it in the other attr-related layout methods to remove a pretty big
source of rampant unsafe code between script and layout.
Event dispatch rewritten to align to spec, activate on clicks better
I went over the changes to the event dispatch spec that had accumulated over the past few years, rewriting dispatch/invoke/inner-invoke almost completely and modifying other code where it was relevant. Most of the remaining obvious deviations from spec are things that will only come up when we start handling events in shadow DOM.
I am pushing now because I want to see CI test results, but please do not approve this PR just if automated test improvements look good. I may have broken some actual UI interactions in the course of fixing synthetic events, and some manual testing is needed, including checking that manual interactions with interactive content continue to fire the events they're supposed to.

Simplify and fix iteration over radio button group
- Code for iterating over radio button group elements has been extracted to `radio_group_iter`
- `in_same_group` now checks if elements are in the same tree
- `radio_group_name` returns `None` if name is empty
- Radio buttons now group together in orphan trees (#25486)

Issue 21810/improve validation methods
<!-- Please describe your changes on the following line: -->
This is a start at addressing #21810. I'm putting these changes out early to get some feedback on the following items:
1. I added unit tests for the validation methods mentioned in #21810, because I couldn't tell whether any of the existing WPT tests covered them. Are these tests worthwhile? Are any of them unnecessary?
2. I changed the implementation for `is_valid_floating_point_number_string` so that it passed the tests. The previous version of the function wasn't restrictive enough (it allowed certain whitespace characters before the number string).
3. I changed the catch-all condition in `htmlinputelement.rs` to account for the remaining input types that don't have a value sanitization algorithm. This last change seems good to me since we won't be able to add a new input type without adding it to the case and checking the spec for an algorithm.

Replaced catch-all with explicit case for inputs that do not have
a value sanitization algorithm. This should prevent us from
forgetting to implement a sanitization for an input, since they
must all be accounted for in the match expression.

Dispatch composition events in JS.

CompositionEvents currently can only be

I moved away from the `Window` struct all the logic to handle task
sources, into a new struct called `TaskManager`. In a happy world, I'd
be able to just have there two functions, of the types:
```rust
fn task_source<T: TaskSource>(&self, name: TaskSourceName) -> Box<T>
fn task_source_with_canceller<T: TaskSource>(&self, name: TaskSourceName)
-> (Box<T>, TaskSourceCanceller)
```
And not so much duplicated code. However, because TaskSource can't be a
trait object (because it has generic type parameters), that's not
possible. Instead, I decided to reduce duplicated logic through macros.
For reasons[1], I have to pass both the name of the function with
canceller and the name of the function without, as I'm not able to
concatenate them in the macro itself. I could probably use
`concat_idents` to create both types already defined and reduce the
amount of arguments by one, but that macro is nightly only. At the same
time, not being able to declare macros inside `impl` forces me to pass
`self` as an argument.
All this makes this solution more verbose than it would be ideally. It
does reduce duplication, but it doesn't reduce the size of the file.
