Hi Anca, are you able to create a reduced test case for this? When I log in to LinkedIn I don't see the getting started steps.

I hope this is helpful! Also, I've made a second screencast to be easier to identify the affected area: https://drive.google.com/file/d/1HtF743wWir6hCLVYhRLaTFlBzH6SnSOj/view?usp=sharing . If anything else, please let me know!

Thanks Anca! That helps a lot!

Looking into this it appears to be because the :hover is specified on a child of a <button> (a <span> in this case) and that doesn't work due to bug 843003 which has been resolved as a dupe of bug 1089326.

If LinkedIn want to work around this the usual advice is just to move the :hover selector to the button instead of the span:
