Prevent Widows in Tooltips with SASS (Bourbon) or JavaScript?

Question

I have a custom tooltip implemented with SASS (and Bourbon) and would like to prevent widows from appearing, example:

.custom-tooltip {
  @include position(relative);
  .tooltip-right {
    font-family: $brand-font-condensed;
    font-size: 14px;
    font-weight: 400;
    position: fixed;
    text-align: left;
    overflow: visible !important;
    background-color: rgba($dark-gray, 0.95);
    color: #fff;
    padding: 7px 10px;
    z-index: 9000;
    visibility: hidden;
    opacity: 0;
    border-radius: 2px;
    box-shadow: 0 2px 5px 0 rgba(#000, 0.16), 0 2px 10px 0 rgba(#000, 0.12);
    @include transition (.1s ease-in);
    @include size(200px auto);
    white-space: normal;
  }

  &:hover .tooltip-right, {
    visibility: visible;
    opacity: 1;
    @include transition (.2s ease-out);
    -webkit-transition-delay: .3s;
    transition-delay: .3s;
  }
}

Are there any preferred way of doing this with just CSS or can this only be correctly calculated with JavaScript? I know I have a width in place but without it the tooltips would just be one big sentence. I do not want to use a plugin because there are lots of different use cases for these tooltips based on the design so I'm doing them by hand. Thanks in advance!

Depending where the tooltip's content is coming from, the best way to deal with this would be to update the content to have a   as the space in-between the last two words.
