Actually all browsers work like this - they have UI and JS running in the same thread, so you can't do anything while a tile is rendered. I've split the process to 3 chunks (styling, map rendering and text rendering) to make the UI a little more responsive, but generally this can't be addressed well at the moment. I'm hoping that browsers will implement the ability to manipulate Canvas in a Web Worker sometime so rendering is in a separate thread.
