Compatibility with React 19 - TypeError: Cannot read properties of null (reading 'props') and Reconciler Incompatibility

### Description

After upgrading to React v19.2.0, `react-pdf` outputs a TypeError to the console, stating that props on this line is null:
```JS
. . .
const render = async function (compress) {
if (compress === void 0) {
compress = true;
}
const props = container.document.props || {}; <--- **ERROR**
const {
pdfVersion,
language,
pageLayout,
pageMode,
title,
author,
subject,
keyboards,
creator = 'react-pdf',
producer = 'react-pdf',
creationDate = new Date(),
modificationDate
} = props;
const ctx = new PDFDocument({
. . .
```

Additionally, a reconciler error occurs seemingly at random. I'm assuming it is happening at unload (see below).

### Steps to reproduce

Set up a React 19 project.
Set up a PDFViewer rendering a document. See error in console.

```TSX

{template}

```

### Expected behavior

Document rendered without errors.

### Actual behavior

Document rendered in window properly, but `TypeError: Cannot read properties of null (reading 'props')` error printed to console.

### Additional information

```
