ad notice has its own css file. do it there

[lianbenjamin]

@yairans it's not working when adding this to ad-notice.scss. the adding of pointer-events:auto to top-bar's children is stronger. we needed to add another level to make this one stronger.

[yairans]

the top-bar itself it also a container so add this in it

[yairans]

with scss you can do like:

  &.disabled {
    pointer-events: none;
    * {
       pointer-events: auto;
    }
  }```

We tried first what you suggested but it doesn't fix the issue correctly. The problem is that the left and right controller also have dimensions due to its children, so it is also grabbing the clicks. That is why we lowered it another level
