Select border color

Question

I don't seem to be able to get rid of the border (outline, box-shadow?) against the select element in Opera browser.

None of the below rules are removing the border:

Opera version is 46.0.2597.57 (PGO).

The above code is working perfectly in other browsers tested - Chrome, Firefox, Internet Explorer and Edge.

Any hint would be helpful.

EDIT I am using Windows 10 64-bit, here is a screenshot:

You can get rid of the border with -webkit-appearance: none;, but this removes the caret too, so you might have to add this again manually. I could not manage to find a better answer to this, since opera is really stubborn with this border. (Updated solution with caret below)

select {
  border: 0;
  outline: 0;
  background: transparent;
  border-image: none;
  outline-offset: -2px;
  border-color: transparent;
  outline-color: transparent;
  box-shadow: none;
  -webkit-appearance: none;
}

<select class="form-control" id="1">
  <option selected="selected" value="0">Most Popular</option> 
  <option value="1">A-Z</option>
  <option value="2">Z-A</option>
  <option value="3">Lowest price</option>
  <option value="4">Highest price</option>
</select>

Updated solution: This is more like a workaround, than a solution, but this has a working "fake" caret, and looks like a borderless dropdown, even in Opera.

select {
  border: 0;
  outline: 0;
  background: transparent;
  border-image: none;
  outline-offset: -2px;
  border-color: transparent;
  outline-color: transparent;
  box-shadow: none;
  -webkit-appearance: none;
  width: 100% ;
  position: absolute;
}

.select-wrapper {
  position: relative;
  max-width: 100px;
}

.select-wrapper:after {
  content: "\25BE";
  float: right;
  margin-top: -3px;
}

<div class="select-wrapper" id="label-for-1">
  <select class="form-control" id="1">
    <option selected="selected" value="0">Most Popular</option>
    <option value="1">A-Z</option>
    <option value="2">Z-A</option>
    <option value="3">Lowest price</option>
    <option value="4">Highest price</option>
  </select>
</div>
