CSS word-break property

Bartik theme has CSS word-break property in its CSS components:

core/themes/bartic/css/components/comments.css, line 67

.comment__content {
  position: relative;
  display: table-cell;
  padding: 10px 25px 10px 25px;
  vertical-align: top;
  width: 100%;
  border: 1px solid #d3d7d9;
  font-size: 0.929em;
  line-height: 1.6;
  word-break: break-all; /* <- This one should be eliminated. */
}

I consider this as a bug, because it's hard to read comments this way.

In fact, I'm creating this issue just because users' complaints (one of my sites uses Bartik theme, I'll switch to the custom theme soon enough, but I believe this "bug" should be fixed in Bartik as well). After all, we create sites for the end real users, and if something breaks user experience - it should be considered as a bug, and be fixed (I understand where this property comes from, full responsiveness and all - but not at this expense).
