When merged in, will introduce the same focus behavior that was introduced for Multiple Choice in HFP-3554: For both "Check" and "Show Solution" move the focus to the first answer. When calling showSolutions programatically, e.g. by a parent content type, the focus is not set.
background
Currently, the behavior of Mark the Words is a little odd.
When clicking on "Check" or "Show solutions", the focus will be given to an invisible and non-tabbable element above the text in order to announce "Checking Mode" an to allow navigating forward through the answers, but not in tabbable lists anymore. The user will not have to use text navigation.
