Current behavior 😯

I'm trying to create a layout (base).tsx at the root level for the route group (base) with the following structure:

|-- routes/
    |-- (base).tsx   <-- layout
    |-- (base)/
        |-- index.tsx
        |-- about-us.tsx
    |-- admin.tsx    <-- layout
    |-- admin/
        |-- dashboard.tsx

Doing so causes a hydration error when rendering one of the pages in the (base) route group.

Expected behavior 🤔

No hydration errors, and everything renders as expected.

Steps to reproduce 🕹

Steps:

1. Start a new solid start project
2. Create a route group with a layout at the root level, similar to the one in the "current behavior" section
3. Navigate to one of the pages in the route group
4. Hydration error

Context 🔦

I want to create two different layouts for admin and non-admin pages. I want non-admin pages to be at the root-level, with admin pages under the /admin route.

I've read through the documentation for SolidStart routing, but it doesn't seem to address this caveat, so I am unsure if this is a technical limitation or just an oversight.

Here are route structures I've tested:

Hydration error:

|-- routes/
    |-- (base).tsx   <-- layout
    |-- (base)/
        |-- index.tsx
        |-- about-us.tsx
    |-- admin.tsx    <-- layout
    |-- admin/
        |-- dashboard.tsx

No hydration error, but no layout:

|-- routes/
    |-- (base)/
        |-- index.tsx
        |-- about-us.tsx
    |-- admin.tsx    <-- layout
    |-- admin/
        |-- dashboard.tsx

No hydration error with layout, but not root level:

|-- routes/
    |-- test/
        |-- (base).tsx   <-- layout
        |-- (base)/
            |-- index.tsx
            |-- about-us.tsx
    |-- admin.tsx        <-- layout
    |-- admin/
        |-- dashboard.tsx
