material-ui docs OOM after intersectionState propagation in relations

While redoing benchmarks for the 5.0 RC blog post, I foud that material-ui's docs now OOM.

A bisect points to #52392, and reverting this PR makes things compile at a reasonable speed again.

Steps to reproduce what I'm doing exactly:

```
$ git clone https://github.com/mui/material-ui.git
$ cd material-ui
$ yarn
$ node ~/path/to/tsc.js -p ./docs
```
