Url updates, but page isn't rendered

[Tyler-Petrov]

Describe the bug

This bug is inconsistent. Sometimes when click an <a href="..."></a> the url will update but the page that was navigated to won't render. Updating the url params triggers the page to render. There are no errors in the console. The navigating object has defined properties.

Reproduction

I have not found a way to reliably reproduce this error

I thought I'd add my svelte.config.js file here. I have data-sveltekit-preload-data="hover" on the body tag.

import adapter from '@sveltejs/adapter-vercel'
import { vitePreprocess } from '@sveltejs/vite-plugin-svelte'

/** @type {import('@sveltejs/kit').Config} */
const config = {
	preprocess: vitePreprocess(),

	kit: {
		adapter: adapter(),
		paths: {
			relative: false,
		},
		alias: {
			$lib: "./src/lib",
			$src: "./src",
		},
		experimental: {
			remoteFunctions: true,
			tracing: {
				server: true
			},
			instrumentation: {
				server: true
			}
		},
		version: {
			pollInterval: 5 * 60 * 1000,
		}
	},
	compilerOptions: {
		experimental: {
			async: true
		}
	}
}

export default config
