This morning I started the Introduction to the CSS Flexbox Challenges and found the lesson links are not working properly (for me at least).
Left clicking the Go to the first lesson button presents the lesson “Use the align-items Property in the Tweet Embed” . Note the URL versus the lesson title on the left page shown in the image included below.
Right clicking and selecting Open Link in New Tab seems to present the proper lesson. Again, note the URL in the page on the right.
Interestingly, copying the URL shown on the left and pasting it into a new tab presents the page shown on the right.
Similar behavior occurs for the individual lesson links on the Intro page.
Could this be something specific to my browser instance or a legit bug?
