Hiding visually dependent content is useless

I expected the "hide visually dependent content" to hide visually dependent content but still allow me to use the site, but it doesn't, the content it was supposed to hide is still there, except with a message telling me to turn off the setting.

I have trouble counting a bunch of the same thing as the items blur together in my mind, so I toggle the "hide visually dependent content" setting on. So, I was quite surprised when the counting things weren't hidden for me. Instead, I got a pop-up telling me to toggle the setting off, and below the pop-up is`the content the setting was supposed to hide. This is another example of khan academy's refusal to institute basic accessibility features in their website.

Support categorized the issue as "solved" but its not and they don't even see the problem with this, This isn't accessibility, this is just making it harder for disabled people. It is literally making things LESS accessible when its turned on, and the support person has the AUDACITY to say khan cares about disabled people. HA. Fix your website and focus on accessibility instead of AI.
