Bug: Slow Performance in Safari with Large Character Counts

Lexical version: 0.13.1 (Vanilla JS)

## Steps To Reproduce

1. Access the CodeSandbox example: [Link](https://codesandbox.io/p/sandbox/lexical-vanilla-js-forked-yd7r7t?file=%2Fsrc%2Findex.js).
2. In Safari, type quickly in the first editor.

## The current behavior

**Issue:** Persistent input latency is observed in the initial editor, unaffected by previous solutions like `outline:0;`.

**Observation:** Additionally, when lag occurs and the user switches to a second editor, the input unexpectedly continues in the new editor.

## The expected behavior

**For the Issue:** The expectation is for the editor to handle rapid typing smoothly, without noticeable delay.

**For the Observation:** Inputs should remain in the originally intended editor, or stop as explained [here](https://github.com/facebook/lexical/issues/4239).
