The intermittent failures are hard to pin down and they can be in many different tests.
Often you can see the element you are targeting in the browser but the program just doesn't seem to be in sync and can't find it. All attempts to wait don't work because of the disconnect with the actual page showing the element you want.
This has been the case in various ways for a couple of years and huge attempts by us to eliminate the failures with various capybara wait methods have helped but not eliminated the issue.
What else can we try?
