1423772 - Learning module hyperlinks causing odd behavior

Status: RESOLVED WORKSFORME

What did you do?
================
In the module "CSS" > "Styling text" > "Stying links", some of the hyperlinks are causing odd behavior.

1. In the "Default styles" example, clicking "A link to the Mozilla homepage" causes the link to disappear, and nothing is replaced in the box where it was.  Reloading the page doesn't help, and the browser's back button isn't enabled so that won't help either.  The only ways I've found to get the link to show up again are to click the appropriate module link in the bar on the left side, copying the module URL and pasting it into the address bar to manually load the page, or closing the browser window and navigating to the module in a new browser window.  I'm using Windows 7, Mozilla Firefox 57.0.1.  I checked for Firefox updates but I got a message that I'm up-to-date.  I tried to figure out the problem by looking at the Page Inspector but quickly realized I was in over my head.  I did find though that the problem isn't just visual.  If I search for "homepage" using the Inspector search feature, before clicking the link there are 6 instances; after clicking the link (and it disappears) there are only 5 instances.

2. In the "Styling some links" example and "Active learning:  Style your own links" activity, I get similar results to # 1 when I click the "Mozilla Firefox" and "Microsoft Edge" links.  In addition, in the active learning area, clicking on "Mozilla Firefox" or "Microsoft Edge" not only blanked out the window but it also made the "HTML Input" and "CSS Input" windows disappear.  Clicking on "Google Chrome" brings up the Google Chrome page in the example box.  Please note that once I realized there was a problem, I started each of these one at a time in a brand new browser window to try to understand the behavior.  Using an old window sometimes allowed me to reload the page successfully, or sometimes clicking the browser back or forward button might reload the page successfully (though sometimes I had to manually reload the page using the browser's reload button).  All three URLs in separate browser windows work just fine.

3. In the "Including icons on links" example, clicking the "weather page" link gives similar results to # 1.  Clicking "weather on Wikipedia" actually opens the appropriate Wikipedia page in the example box.  Clicking "weather on Extreme Science" does nothing, as if the hyperlink was just # like in some earlier modules instead of an actual URL.  All three URLs in separate browser windows work just fine.

What happened?
==============
Please see above.  It almost seems like a different web page was being loaded (like maybe a previous version that wasn't completely coded and populated yet), but the URL didn't change during my testing.

What should have happened?
==========================
Clicking the hyperlinks should have loaded each page chosen in the box and left the other boxes alone.  Also, the browser reload button should have reloaded the page as if I had just opened that page for the first time (unless I misunderstand the function of the browser reload button).

Is there anything else we should know?
======================================

Looks like this is fixed now.
