Steps:
Repro steps: 
# Enable ChromeVox with ctrl + alt + z
# Create any site from sites.google.com in the "new sites" format, add a text box if there isn't one already
# Navigate anywhere outside of the text box (for example, refresh the page)
# Navigate back to the text box

Expected: text box is in tab order or you are able to use linear navigation to get into it

Actual: not in tab order, linear navigation is ignored in M68 and M69 per bug 894246 (though in linear nav order in M71)
