paste text comes with background-color

[bgomes90]

Hello, what's up?
When I copy text from a document (word, pdf, etc) and paste it into the quill editor, it comes with the style="background-color: transparent".
But I need to generate a pdf of this document, and when I generate the pdf, this background-color: transparent turns into background-color: black, and no text appears.
Is there any way I can remove all the styles applied to the html when there is a change in the quill?
Thanks in advance.
