Research direction

Start with the linked CodeSandbox and reproduce the cursor jump while typing, using DynamicFormControlComponent, and during an external subscription update. Trace the Angular component's value-update handling; done means each update preserves the cursor position instead of moving it to the start, including on Angular 13 and latest.

Written by the indexing model from the issue text.

Description

Updating content externally or using DynamicFormControlComponent to update the value causes the cursor to jump to the start of the rich text editor. This issue also happens if there is another subscription firing to update the value somehow while typing

https://codesandbox.io/s/tinymce-angular-forked-sdwgoj

while typing it should not jump to the start, updating the value externally should not jump to the start, and after updating the value it should not jump to the start
