   `zr_100000` is a special `zlevel` that provided to the hover layer.
   
   SVG rendering mode is not good at animation performance because each frame it needs to find out which DOM needs to be updated and manipulate the attributes of DOM. Even if we did lots of optimizations, it's still not as fast as Canvas. Especially in a case like this map which has lots of elements. The advance of SVG rendering mode is reducing the memory usage on mobile devices.
