In ankidroid: when editing a long answer, the cursor jumps to bottem of card. How to stop this?

When I’m working on a longer answer card with several clozes, and I want to remove some whatever code that came by copy/pasting text - for example letter type etc. I want to remove that to make the card more lisable. Anyway, whenever i am working in some paragraph, the cursor jumps to the bottem of the card and I have to search again where I was editing/deleting code.

How can I make that jumping to the bottem stop ?

Thank you
