The deleted code ensured that a static variable wouldn't update when it's in the same text expression as a reactive variable. We solved this through emitting a warning about this instead, marking it as undefined behavior.
- doesn't add spread_dynamic_element_attributes when there are no attributes — Unnecessary spread_dynamic_element_attributes call #9646
- skips the child render function altogether if there is nothing to do
If someone has an existing SvelteComponent type definition and using the slot generic to type the default slot, automatically add that slot to the prop type as "children"
The original intent was for typing generation tools like svelte2tsx to use the virtual constructor instead, but it does more harm than good. Most notably, the TS error message when props are wrong becomes completely useless. It's better for tooling to silence the deprecation message and switch over to a new virtual constructor once we remove the deprecated one.
