Preventing focus when text gets added to document

Hey all,

I have added a video of my application, which has an unintended event happening.
As soon as I type in the field on the left, this code will be executed:

  updateField(): void {
setTimeout(() => {

As you can see, what I'm trying to prevent is the editor from catching the focus of the browser by immediately refocusing on the input element. Sadly, just for the most brief moment, it still loses focus. I just want to be able to type in a field on the left to insert text on the right. The reason should be clear, shifting the focus isn't what I want, this causes a lot of accessibility issues and some other coding issues.

I tried catching and preventing the event with this code, but it doesn't seem to be able to stop the behavior (It's also the code that shows the logs in the video):

  @HostListener('document:focusin', ['$event'])
onFocus(event: FocusEvent) {
const target = event.target as HTMLElement;
if (target && target.classList.contains('e-de-text-target')) {
console.log(`Element focused: `, event.target);

The code that updates the text in the document editor is your basic code:

updateQuestion(id: string)


const preview = this.swiftPreview?.documentEditor;






I really need to fix this, since this causes to many issues.
If there is another way to better replace text in any way that prevents this it would be awesome to.
