Talkback announces non-meaningful content (e.g. "start X pixels") as user navigates markdown content

Bug Description

Talkback announces things like "start X pixels" as user navigates markdown content

Steps to Reproduce

Steps to reproduce the behavior:

1. Run sample Android app
2. Turn on talkback
3. use swipe navigation to listen to content

Expected Behavior

Talkback does not contain layout information (if that's what it is?) like "start 100 pixels" or "end 100 pixels" that may confuse a talkback user.

Actual Behavior

Talkback announces things like "start 100 pixels" or "end 100 pixels".

Screenshots (turn on player audio to hear talkback)
