Mapbox event when brand new tile is loaded

Question

I'm using Mapbox GL JS API to manipulate a Mapbox map. My question if there's an event that's capable of telling me for each HTTP request for new tile? I finish with a code like this:

  map.on("dataloading", e => {
   if(e.dataType === "source" && e.source.url && e.tile) {
     //Fresh HTTP request to Mapbox API ?
   }
  });

Im using this & this docs

It's not the primary purpose, but you should be able to use map.transformRequest to achieve this goal. It gets called for every request, so you'll just have to check whether it's loading a tile or something else.
