Description

Issue Description
The Editor component freezes when pasting large text. In Taiga v2.99.0 or 4.x, pasting the same text into the Editor works instantly.

Steps to Reproduce:

1. Copy the provided text from the attached file. 1 (2).txt

2. Navigate to the Editor component page in Taiga UI v3.

3. Paste the text into the Editor.

Actual Result:
The code execution in the main thread takes 5-6 seconds, blocking the UI and making it unresponsive.

Expected Result:
Pasting text should be as fast as in the Editor[new] component of Taiga UI v2.99.0 or Taiga 4.x, with a response time of less than 1 second.
