Bold-ing in Safari

The bolding in Safari look off to me. Please see the image below, has anyone else experienced this?

If you do have experience with this, do you have a solution?

Two questions:

  1. How does a screenshot of the same app/URL look when taken in Chrome?

  2. Can you show us what the fonts are computing as in inspector? Right-click on those bold titles, inspect element, and then the computed tab on the right. There should be values for font-family, font-size and font-weight.
