* Given a list of prop objects, merges them into a single object.

* - Automatically composes event handlers (e.g. `onclick`, `oninput`, etc.)
|
|
* - Chains regular functions with the same name so they are called in order
|
|
* - Merges class strings with `clsx`
|
|
* - Merges style objects and converts them to strings
|
|
* - Handles a bug with Svelte where setting the `hidden` attribute to `false` doesn't remove it
|
|
* - Overrides other values with the last one
