When I changed the "Enable Preview" option in Preference, I found that it couldn't be selected, and every time I changed it to select and then switched to another Tab, it resets Toggle's state to false, causing the Hover Preview feature to not work. I found out that it was because "Enable Preview" in "smart_hierarchy_settings.uxml" didn't set bindbing-path.
