Why is the src attribute of the image not saved in the text editor when specified in the data: URL format?

Question

SharePoint

There is a picture in the input field, it is displayed, but after saving the post, the src attribute of the picture becomes empty. Can this be fixed?

Answer 1

Perhaps SP cuts off all prohibited tags or embeddings (this can also apply to the embedding of some JavaScript pieces, too), you can look in the security policies in the Administration Center.
