ngx-select caret scales inconsistently

[mcwenger]

.ngx-select-caret is sized with em units, so it appears smaller than the expected default when a parent container has a declared em/rem font size.

@mcwenger Is the expected behavior here that both the .ngx-select-caret and the .ngx-select-clear maintain their fixed size, or should they both grow/shrink relative to the component font-size property? At the moment .ngx-select-caret is using relative units as you pointed out, while the .ngx-select-clear button has a fixed px size, which causes a visual inconsistency. E.g.:

ngx-select {
  font-size: 2em;
}

IMHO it'd look better if both buttons grew with the rest of the text around them, but it's up to you. Please advice, and I'll take care of this one. Thanks.
