TextArea - fix scrolling

[thrbnhrtmnn]

Step-by-Step Guide to reproduce

The issue seems to only be happening in Firefox. On Chrome and Safari it is working as intended right now.

1. Navigate to https://b01ler.onrender.com/?path=/docs/design-system-web-components-forms-text-area--docs or https://b01ler.onrender.com/js-example-app
2. Find textarea
3. Ensure the Text Area is small enough, so scrolling will be enabled when enter some text (by reducing the size)
4. Start typing
5. See that once a few lines are filled with a value, the Text Area is scrolling up and down with every new input

Hey @larserbach , I created the issue, but I could not replicate the behaviour from the video, could you add more information about the issue to the description?

I searched for the error and found out: If I remove the keyup event on line 165 in the index.ts which update the counter, then it works well. Maybe this event could be adapted or like that?
Update:
I try this [fix/712-fix-scrolling] (https://github.com/deven-org/B01LER-Kitchen/tree/fix/712-fix-scrolling)

After merge we can move this to done as complete. No open topics from the design review.
