Related issues links have an insufficient line height

Agree. It is set to 1.2em. Increasing to 1.4em is sufficient - see the screen shot attached.
(oh, I can't attach here, will do that after saving)

Showing the change from 1.2em to 1.4em

so like this.

Not being aware of the parallel universe of this issue queue, I filed #2194805: Link text overlaps itself in Related issues views block in the Bluecheese queue. :-(

I'd rather recommend to go with this:

/* Fix insufficient line-height for links in related issues block. */
.project-issue-status-info a {
  line-height: 150%;
}

That is, because this is the style from which the offending padding originates from. Hence, that existing style is the style that is responsible for taking care of a potentially wrapped line.

Before vs. After

I've got your css up here:

Looks way better than here:
https://drupal.org/node/2150405

Patch is attached.

EDIT: Thanks for the code @sun!

Moving to the proper project for review.

Module CSS should be kept minimal, since themers often do not like default styles. This should go into Drupal.org's theme.

I think this would go in either:

• sass/partials/common/_lists.scss because this is a list.
• sass/partials/drupalorg/_issue-page.scss because this is on the issue page.
