RoboHelp 2019 - Responsive HTML 5 and Search Highlight Toggle

In RoboHelp 2017 Responsive HTML 5 output, you can't toggle search highlight on and off (like you can in CHM or WebHelp output). (You can manually edit the code to turn it off completely, but end-users can't toggle it on or off.) Is the search highlight toggle now available in Responsive HTML 5 output?
