Merge pull request #297 from ckeditor/t/ckeditor5/1870
Fix: Image widgets should not span the entire width of the editor. Closes ckeditor/ckeditor5#1870.
BREAKING CHANGE: From now on, all images in the editor use CSS `display: table` by default (`.ck-content .image { display: table }`). It can affect integrations and we recommend checking if images render correctly in your project after this update. There is a possibility you might need to adjust the CSS to adapt to this change.
