Changes proposed in this Pull Request:

can create a variation option and publish the product sometimes fails because the first element matching the created size ('Small') can be hidden and the test expects it to be visible. Example.
Updating the assertion to check that the variation input field contains the expected text would hopefully fix the issue.
