turn off horizontal line announcement

macOS & Mac Apps

on many wetsites, the author often draw a horizontal line, presumably to make the page look good, like this:

if you look under the first heading, there are several such line, and vo announce them as "dimmed collapsed on top horizontal rule".
the question is how does one turn this announcemebnt off? i tried customizing the verbosity settings, the obvious suspects are "rule marker" and "spliter", and i also tried many others, none of them worked for me. any way to turn this thing off? sometimes there are so many sucn horizontal lines, it's very annoying and time wasting.
