Demonstration of bug in mapbox-gl 3.1.2

How to reproduce:

• Clone repository
• Create .env file with variables according to .env.sample
• npm install
• npm start
• Hover over a rendered tree circle -> opacity should change and 3D model should scale bigger
• Change number of rendered trees (numTrees variable) in ./src/Map.js and reload
• For small numbers < 50 (exact number unclear), everything works fine
• For larger numbers (in my case, > 100 works reproducible), the hover effect still works on the circle, but it stops working on most of the 3D models. Weirdly enough, some randomly selected 3D models still work.
