Some of the "testing" web pages (and scripts) have become quite large, with many sample/test elements.
Part of the problem of this is that when a test runs, the screenshot shows the testing element scrolled off of the visible area of the page.
The test website should be reworked so that each test page (and its backing script) has only the web elements to perform tests upon a single feature. They should be named such as PageWithASelectElement or PageWithADateField etc.
