Better tracklist rendering performance #175

As soon as you render more than ~200 tracks you feel the browser freezing on an M2 MacBook. This is primarily due to 1) the amount of javascript work each <r4-track> and its child components do, and 2) the CSS layout for so many elements.

This PR

  • conditionally renders the dialogs inside r4-track, only when the menu is actually open (this makes the difference)
  • uses content:visibility css trick on r4-list-item to allow the browser to optimize rendering depending on viewport

The branch also touches on the query, filter and search components to eliminate double-fetching.

this.setInitialValues()
this.onQuery()
// console.log('r4-supabase-query:connected->dispatching query', this.query)
// this.dispatchQuery()

The mention and tag links on r4-track no longer work well with the query url stuff. HMMMMM

Meh can't figure this filter query url params stuff out for now. Closing in favour of #176
