Destructuring inline event parameters breaks IntelliSense

[ignatiusmb]

Describe the bug

Having an inline event handler inside an element (doesn't have to be a special element) breaks <style> tag IntelliSense.

Reproduction

Copy and paste the snippet to an empty .svelte file and trigger the autocomplete box in the styles tag

<svelte:window
    on:mousemove={({}) => {
        // destructuring the parameter above breaks autocompletion
        // remove the empty brackets and the css autocompletion below works
    }}
/>

<div><slot /></div>

<style>
    div {
        /* trigger autocomplete here, gets JS variables instead of CSS */
    }
</style>

Expected behaviour

CSS autocompletion works without having to move destructuring inside the function body.

Its not just for destructuring (though I can replicate that as well). In this snippet, it breaks with the same symptoms:

<svelte:window
    on:mousemove={() => {
        if (true) {return}
        if (2 >= 1) {}
    }}
/>

<style lang="scss">
    /* js suggestions here :// */
</style>
