vuetify.js v-select minimum height limitation?

Question

As you can see from below, I am trying to reduce the height of a v-select element, but it appears there's a limit to the minimum height I can set. i.e. after height = 40, further reducing the height doesn't seem to work anymore. Is there anyway to surround this limit so I can make this element smaller? I need this because I need to fit it into a relative small div. Thanks in advance -

new Vue({
  el: "#app",
  data: {
    years: [2015, 2016, 2017, 2018]
  }
})

The min-height of v-select component is 56px which is defined by the following CSS rule :

     .v-text-field--box .v-input__slot, .v-text-field--outline .v-input__slot{
       min-height:56px;
     }

let's override it for example by setting :

  .v-text-field--box .v-input__slot, .v-text-field--outline .v-input__slot{
   min-height: auto!important;
  }

but the result it's not perfect and the content is not aligned properly, to fix that we gonna add the following properties to the above rule :

  display: flex!important;
  align-items: center!important

new Vue({
  el: "#app",
  data: {
    years: [2015, 2016, 2017, 2018]
  }
})

.v-text-field--box .v-input__slot,
.v-text-field--outline .v-input__slot {
  min-height: auto!important;
  display: flex!important;
  align-items: center!important;
}
