[Vuejs]-Font awesome icons size jumps in first load of a static page with vue.js

you have written below style in vue component, can you move it in a css file:

.svg-inline--fa.fa-w-10 {
    width: 0.625em;
}

The problem is app.js file has the above css, so it’s taking time to load and once the file is loaded in DOM then you are seeing the effect.
