CSS Animations example doesn't work

[caburj]

Describe the bug

Navigate to the CSS Animations example and it won't render anything because it crashes with the following error:

eruda:8 Console was cleared

Hmm.. the example works in codesandbox: https://codesandbox.io/s/basic-css-transition-36rln

So probably something specific to playground/website. I will transfer the issue there.

Ok this is interesting

When you change the import to from "solid-transition-group@beta" instead, everything works. Even though @latest and @beta are at this time exactly the same.
The only difference between the two is when they were published.
@beta was published when [email protected] was the latest version, and @latest was published a couple of hours after [email protected] has been released.

solid-transition-group:

solid-js

and @solid-primitives/transition-group (dependency of solid-transition-group)

Solid playground uses esm.sh for fetching packages, and so if you request the solid-transition-group package, this is what you get: https://esm.sh/v111/[email protected]/es2022/solid-transition-group.development.js

/* esm.sh - esbuild bundle([email protected]) es2022 development */
// esm-build-33e8763ed2a9c598ebef3ca4126942e11623bd31-c42d8a64/node_modules/solid-transition-group/dist/index.js
import { createMemo } from "/v111/[email protected]/es2022/solid-js.development.js";
import { createSwitchTransition } from "/v111/@solid-primitives/[email protected]/es2022/transition-group.development.js";
import { resolveFirst } from "/v111/@solid-primitives/[email protected]/es2022/refs.development.js";
import { createEffect } from "/v111/[email protected]/es2022/solid-js.development.js";
import { createListTransition } from "/v111/@solid-primitives/[email protected]/es2022/transition-group.development.js";
import { resolveElements } from "/v111/@solid-primitives/[email protected]/es2022/refs.development.js";

It requests solid-js version 1.6.15

But when you request the @solid-primitives/transition-group dependency:
https://esm.sh/v111/@solid-primitives/[email protected]/es2022/transition-group.development.js

/* esm.sh - esbuild bundle(@solid-primitives/[email protected]) es2022 development */
// esm-build-816576961470e1bbc287410f58437464a2dc660c-fa40c853/node_modules/@solid-primitives/transition-group/dist/index.js
import { untrack, createSignal, useTransition, createComputed, batch, createMemo, $TRACK } from "/v111/[email protected]/es2022/solid-js.development.js";

It requests solid-js 1.6.14

But then, when you request for solid-js - version used by your code in the playground
https://esm.sh/solid-js?dev

/* esm.sh - [email protected] */
export * from "https://esm.sh/v111/[email protected]/es2022/solid-js.development.js";

It responds with 1.6.14 😅

So both playground and solid-transition-group are working fine. It's just that they are using different solid versions - which breaks the usual execution of effects - because esm.sh responds with inconsistent solid-js versions.
No idea how exactly we are supposed to fix that.
