Fixes #23447 (closed).
Current calculations are wrong for me.
First we shouldn't multiply border by two. Second we should add (not substract) border to padding.
Also we want the same line-height like .form-control have.
Without line-height .from-control-plaintext isn't properly aligned with *-sm/lg modifiers.
We can avoid calc() too. Just add to .col-form-label border:
border: $input-btn-border-width solid transparent;
