Research direction
Investigate the LIcon component in Vue2Leaflet (likely LIcon.vue) to understand why createIcon is called every frame. Check if the leaflet icon instance is being recreated on each update due to Vue reactivity. Consider using computed properties or caching the icon to prevent re creation. Look at the jsfiddle demo to reproduce and confirm the issue. Explore Leaflet's Icon documentation for proper usage.
