Is your feature request related to a problem? Please describe.

When pasting formatted text in a text editor such as Trix editor it will also upload an image.

Describe the solution you'd like

Adding the tags to the ignore list as done with textarea and input. #493

Describe alternatives you've considered

Adding an option to provide a custom tag to add in the ignore list.
This would be more flexible when other editors are used.

Perhaps you can call stopPropagation() on the paste event when captured in the textarea?
