>> The original purpose of this issue was to fix the problems of elements on the deprecated API list that can't be deselected because their release is not included in the list of checkboxes at the top of the page. This is fixed here by adding a checkbox for all elements/releases not included in the list if necessary.

This includes the case of a single release (where a checkbox doesn't make any sense) and the case of some or all releases not having any occurrences in the `since` element of deprecated elements (in which case the checkbox is useless as well). A more detailed description of these cases is available in the [JBS issue](https://bugs.openjdk.java.net/browse/JDK-8287524).
