(This ASCII art violation uses aria-labelledby. Please note that aria-label, aria-describedby or title can be used instead.)
(This ASCII-art is wrongly hidden using aria-hidden. Please note that role="presentation" can also be used to hide decorative elements.)

This meaningful ASCII is wrongly hidden using aria-hidden:

ASCII art of a full-body cat sitting.

      /\     /\
     {  `---'  }
     {  O   O  }
     ~~>  V  <~~
      \  \|/  /
       `-----'____
       /     \    \_
      {       }\  )_\_   _
      |  \_/  |/ /  \_\_/ )
       \__/  /(_/     \__/
         (__/

Note: Hard to implement because it requires using AI / human to determine whether the ASCII art is truly meaningful, and then ensuring that it is not hidden from acessibility tree.
