Dialog component & JAWS screenreaders

Hello - we noticed some slightly unexpected focus behaviour on the dialog component in testing the other day. Testing was conducted using the JAWS screenreader.

Issue
When you use the ‘start’ button, focus jumps briefly to the top of the page before then being moved to the first item when it appears.

Then, when dialog items appear, they each take focus sequentially without any user intervention. The focus movement is essentially timed based on the appearance of the dialog component items.

Request
Could the user be in control of focus or could focus just move to the first item, allowing the user to then engage with the others as they would in components like the text and graphic, media grid etc.
