[BUG] Overriding the default render fails when using the built in InlineCSUIContainer or OverlayCSUIContainer

[cheesestringer]

What happened?

Following the docs at https://docs.plasmo.com/framework/content-scripts-ui/life-cycle#renderer to override the default render using the built in Inline Container or overlay Container fails with the error: Cannot read properties of undefined (reading 'type') at injectAnchor (csui.ts:58:14).

To reproduce create a new content ui script with an InlineCSUIContainer or OverlayCSUIContainer.

InlineCSUIContainer:

import type {
  PlasmoCSConfig,
  PlasmoCSUIJSXContainer,
  PlasmoRender
} from "plasmo"
import { createRoot } from "react-dom/client"

export const config: PlasmoCSConfig = {
  matches: ["https://*/*"]
}

const InlineDemo = ({ anchor }) => <span>{anchor.innerText}</span>

export const render: PlasmoRender<PlasmoCSUIJSXContainer> = async (
  { anchor, createRootContainer },
  _,
  InlineCSUIContainer
) => {
  const rootContainer = await createRootContainer()

  const root = createRoot(rootContainer)
  root.render(
    <InlineCSUIContainer anchor={anchor}>
      <InlineDemo anchor={anchor} />
    </InlineCSUIContainer>
  )
}

export default InlineDemo 

OverlayCSUIContainer:

import type {
  PlasmoCSConfig,
  PlasmoCSUIJSXContainer,
  PlasmoRender
} from "plasmo"
import { createRoot } from "react-dom/client"

export const config: PlasmoCSConfig = {
  matches: ["https://*/*"]
}

const OverlayDemo = ({ anchor }) => <span>{anchor.innerText}</span>

export const render: PlasmoRender<PlasmoCSUIJSXContainer> = async (
  { anchor, createRootContainer },
  _,
  OverlayCSUIContainer
) => {
  const rootContainer = await createRootContainer()

  const root = createRoot(rootContainer)
  root.render(
    <OverlayCSUIContainer anchor={anchor}>
      <OverlayDemo anchor={anchor} />
    </OverlayCSUIContainer>
  )
}

export default OverlayDemo
