'span' elements surrounding inline blockable elements set as ephemeral. To be able to set the caret after inline blockable elements, empty 'span' elements are added at the beginning and end of all inline blockable elements. When saving the page these 'span' elements were saved in the page. Setting the class of the 'span' elements as 'aloha-ephemeral' solves this issue, so they will be removed before saving the page.
