Detect when page is done loading

[chudkins]

Need a reliable way of detecting if requested page has loaded completely. Example: After login page, storefront page begins to load; admin link is found but can't be clicked yet because "loading spinner" obscures it.

We need a way to wait until the element we want is available, which in this case means the "loading spinner" has cleared because the in-page scripts are satisfied it's done. Can we also wait for this, maybe by spying on the script?

Selenium web elements have a property "Displayed," which is only True if the element is visible. We might be able to use that in a loop, leaving when the item not only exists but is no longer hidden.

Resolved by WaitFor-ElementToBeClickable, which will wait until either object is clickable (i.e., not obscured) or timeout expires.
