Allow toggle-cards to overflow with scrollbars, #407

[dgileadi]

The filters were there but hidden when there were too many items for the max-height. This changes the overflow to show scrollbars when needed.

I think they just need to be rewritten to use css grid height for animations something like this

.expander {
  display: grid;
  grid-template-rows: 0fr;
  transition: grid-template-rows 1s;
}

.expander.expanded {
  grid-template-rows: 1fr;
}

This is fixed and are arriving in a canary build soon
