When using Live Captions, as new text arrives, a braille display user is interrupted from where they are currently reading and placed at the start of the line

When Live Captions are active, and someone is speaking, the first part of the text will come through and be readable. However, when further text arrives, the braille user is returned to the start of the line and must pan through content to get back to where they were. Tis is only being marked as "moderate" as Live Captions is still in beta.
