The bottom of truncated headings text is not visible

Created by: ysds

When I use a bootstrap heading with text-truncate, the bottom of text is not visible.

I know how to fix it (make line-height equal or larger than font-size). However, I think that it will be very useful if it is defined by default when heading and text-truncate are used together.
