Pasting content into Hallo rich text fields retains HTML text styles from source about wagtail HOT 3 CLOSED

@davecranwell can you sketch out the ideal experience?

from wagtail.

• Pasting into the rich text fields causes an instant reformatting of the content, invoking whatever sanitising occurs when the page is fully saved.
• Any "style" attributes detected during the reformat could trigger a notice above the field to the effect of "Please note: HTML styles detected in this text have been removed."

If the above isn't possible, it might at least be nice to detect style attributes when the paste occurs and alert users that their content won't look the same after saving.

This issue isn't present in Draftail, but of course still present in Hallo. Draftail doesn't display any kind of message, it just strips the formattings that are not whitelisted. Closing.
