No white line

copy the file \node_modules\vue-material\dist\vue-material.css ,
find this class .md-input-container .md-icon:not(.md-icon-delete):after,
delete this attribute content: "",
import this copy to replace your vue-material.css in index.html.
it can resolve this problem,and I didn't find it can cause any problem in other components.
I am looking forward to see the new version of this project.this project is so nice.
Closing this issue as our focus is on the new 1.0.0 version.
