This was done previously to align with browser behavior, but the browser behavior actually only makes them passive on window/document/body. Since wheel events are not delegated, we can revert their passive-by-default setting. Closes#13318
For touchstart/touchmove we're not changing it because these events are delegated, which means they happen a lot more often on a target higher up the tree, which may cause jank.
#13225 did not fully fix the described issue: As soon as you have a child component, that child component's anchor will not be in the right ownerDocument yet, and so the logic falls down.
To fix that, we would need to move the ownerDocument check into the microtask - and that map check was mainly done to avoid just that. So instead I opted to simplify the code and just remove the map checks. According to my benchmarking (https://jsbench.me/3hm17l0bxl/1) this has no impact on performance assuming that you'll have cache hits roughly half the time - and even if you'd have much more cache hits, the performance loss is microscopic. Given that the default mode is to not inject styles, this will not be common anyway, so I favor removing that map.
* feat: provide guidance in browser console when logging `$state` objects
Wrap console.log/warn/error statements in DEV mode with a check whether or not they contain state objects. Closes#13123
This is an alternative or enhancement to #13070. Alternative if we deem it the better solution. Enhancement because it's not as robust as a custom formatter: We only check the top level of each entry (though we could maybe traverse a few levels), and if you're logging class instances, snapshot currently stops at the boundaries there and so you don't get snapshotted values for these (arguably this is a more general problem of $inspect and $state.snapshot), whereas with custom formatter it doesn't matter at which level you come across it.
* lint
* use normal warning mechanism, so we can link to docs etc
* add a few more methods

* fix: escape more template-literal-related characters
Escape `{` at the start of a string, because it could be preceeded by a `$`, which in combination loads to the following characters being treated as a value

* sanitize template strings once assembled (#13263)
* only sanitize template quasis once assembled
* changeset

Our current validation was both too lax and too strict:
- too strict, because you can define a `$` variable in Svelte 4 if it's not at the top level
- too strict, because you can define `$`-prefixed function parameters, but not give the parameter the name `$`
- too lax, because you can define a `$`-prefixed variable if you're at least one level deep into a function. In runes mode, this should be an error
This PR aligns the behavior, ensures this isn't a breaking change in legacy anymore, and makes the validation in runes mode more strict
* fix: follow spec for `customElement` option
* tweak messages, add link to details that will be included on future docs site

This adds a new dev-time only `dev_effect_stack` variable, which executed effects are pushed to and eventually cleared out after everything's settled. If it doesn't settle however, i.e. you run into an infinite loop, the last ten effects are printed out so you get an idea where the error is coming from.
For proper source mapping I also had add location info to the generated effects.
Closes#13192
Fixes#13162
We were going from parentNode to parentNode but if something is a slot of a custom element we should first go to the assignedSlot or else the inside of the custom element will be skipped.

fixes#13194
We narrowed the allowed characters in #13057, but didn't take into account all possible (and for JavaScript identifiers allowed) unicode characters. This widens that, which also removes the accidental breaking change (because in Svelte 4 you were allowed to use these unicode characters).
