When you copy any text containing links, an email address (as link or plain text) or an url (as link or plain text) these links will be included at the beginning of the Rich Text field and mess up the entire text.
Steps to reproduce:
- Install current verions of ez platform
- Edit "eZ Platform" folder
- Copy something like "Hello! Visit our new website www.test.com!" or "Hello! Write us an email -> email@example.com" or any text containing links (e.g. the first paragraph of https://fontawesome.com/privacy) into any Rich Text field
