The Wagtail documentation on Inserting images and videos in a page explicitly states
Half-width left/right aligned: Inserts the image at half the width of the text area. If inserted in a block of text, the text will wrap around the image
How does one implement this?
I have created a page with an Rich Text block and inserted an image in the text (left aligned)
When I publish the page it is not wrapped
What can I do to fix this in Wagtail without the need for an html/css solution?
