This should help everyone who has special needs and use cases around custom elements. Since Svelte components are wrapped and only run on connectedCallback, it makes sense to expose the custom element class for modification before that.
- fixes#8954 / closes#8955 - use extend to attach the function manually and save possible values to a prop
- closes#8473 / closes#4168 - use extend to set the proper static attribute and then call attachInternals in the constructor
- closes#8472 - use extend to attach anything custom you need
- closes#3091 - pass `this` to a prop of your choice and use it inside your component
- add some doc for #8987
When the HTML that is coming from raw html is invalid, the browser reshuffles things. Bail in that case to try to repair more often. Should help with https://github.com/withastro/astro/issues/7557
html tags that could be optimized to use innerHTML in mount ignored any hydration code, which leads to everything getting unmounted and mounted again. This takes the non-optimized path for hydration, too.

This contains a small but unfortunately unavoidable breaking change: If you used `never` to type that the second parameter of `createEventDispatcher` shouldn't be set or that the action accepts no parameters (which the docs recommended for a short time), then you need to change that to `null` and `undefined` respectively

We need to use a different method for getting the meta info because `locate` is used to help construct the source map that references the preprocessed Svelte file. If we would now add source maps to that `locate` function it would go the the original source directly which means skipping potentially intermediate source maps which we would need in other situations. Sadly we can't map the character offset because for that we would need to the original source contents which we don't have in this context.

Can be opt out by setting discloseVersion to false

technically a breaking change because someone with a mutation observer could rely on the order of operations

also add some legacy import paths which should be changed in usage sites ASAP
