closes #7425
Uses a new ensure_array_like function to use Array.from in case the variable doesn't have a length property ('length' in 'some string' fails, therefore obj?.length). This ensures other places can stay unmodified. Using for (const x of y) constructs would require large changes across the each block code where it's uncertain that it would work for all cases since the array length is needed in various places.
`classList.toggle(..., flag)` has been a part of the DOM standard forever,
so better use it instead of possibly causing browser deopts by using dynamic attribute access.
The `!!` is required because an `undefined` flag means flipping the current state.

that way they are invisible to assistive technology and can't be interacted with, which makes sense since the element is already "dead" and only transitioning out at this point

- shard runtime tests for better use of Vite's test parallelization
- merge custom element and other browser tests to run in one test suite and use esbuild in it
- on some setups only generate code output when test fails
Also swap out the require hook hacks with a less-hacky-but-still-somewhat-hacky loader for the Svelte files

This changes the inserted style element for transitions to initially include the string '/* empty */'. This allows you to work around requiring unsafe-inline CSP discussed in #6662 by adding a hash to your CSP:

Fixes #8284.
The problem is that the <slot> element is treated as an actual element, and for this purpose, we have to treat them as if they don't exist. More specifically, we treat all slot fallback children nodes on the same level as the slot's non-slot siblings.
Fixes #4880.
Fixes #6737.
This will be a breaking change for anyone who uses the StartStopNotifier
type in their / implements custom stores.
