Is there any way to prevent the page jumping around as I write a response?

Some of my answers are a few paragraphs long. While I am writing, if another jelly starts to answer the same question, this is flagged – ‘so-n-so is writing a response’ – with an alarming jump on the page.

I’m not sure I need to know someone else is writing at exactly the same time as I am… But I am sure that the jumping about on the page is really annoying! Any feedback here?
