Current behavior 😯

If I nest any jsx tags inside the tag provided by @tanstack/solid-router (example: <Link to="/"><b>Home</b></Link>), it causes the following error:

TypeError: template2 is not a function at getNextElement (http://localhost:3000/_build/node_modules/.vinxi/client/deps/chunk-4JBQOQO5.js?v=a56f0fa8:290:12) at Object.fn (http://localhost:3000/_build/node_modules/.vinxi/client/deps/chunk-4JBQOQO5.js?v=a56f0fa8:675:43) at runComputation (http://localhost:3000/_build/node_modules/.vinxi/client/deps/chunk-IYP4Z4GE.js?v=a56f0fa8:729:22) at updateComputation (http://localhost:3000/_build/node_modules/.vinxi/client/deps/chunk-IYP4Z4GE.js?v=a56f0fa8:711:3) at Object.readSignal (http://localhost:3000/_build/node_modules/.vinxi/client/deps/chunk-IYP4Z4GE.js?v=a56f0fa8:647:67) at resolveChildren (http://localhost:3000/_build/node_modules/.vinxi/client/deps/chunk-IYP4Z4GE.js?v=a56f0fa8:1025:84) at resolveChildren (http://localhost:3000/_build/node_modules/.vinxi/client/deps/chunk-IYP4Z4GE.js?v=a56f0fa8:1029:22) at resolveChildren (http://localhost:3000/_build/node_modules/.vinxi/client/deps/chunk-IYP4Z4GE.js?v=a56f0fa8:1025:68) at resolveChildren (http://localhost:3000/_build/node_modules/.vinxi/client/deps/chunk-IYP4Z4GE.js?v=a56f0fa8:1025:68) at resolveChildren (http://localhost:3000/_build/node_modules/.vinxi/client/deps/chunk-IYP4Z4GE.js?v=a56f0fa8:1025:68)

I created a repo that demonstrates the error here:
https://github.com/kiahjh/ts-router-solid-start-ssr-link-bug-demo/blob/master/src/routes/__root.tsx#L17

Expected behavior 🤔

No error; for instance, a tag should just make the content bold without causing a hydration error.

Steps to reproduce 🕹

Steps:

1. pnpm create solid@latest
2. choose SolidStart
3. choose tanstack-router template
4. Find a <Link> tag and nest some jsx in it

Context 🔦

Specifically, I was building a sidebar navigation component, and wanted nicely styled sidebar links with icons and styled text; but nesting these elements inside a <Link> tag caused the issue described.
