How to use Webix without unsafe-inline keyword for style-src in Content Security Policy (strict mode)

Hi,

We are trying to enable Content-Security-Policy using a meta header in our app running @xbs/webix-pro@8.x.

Already set environment variables to
window.webix_strict = true; | webix.env.strict = true;
as suggested here and here

However, Webix still seems to apply some inline css internally in order to render styling in datatables and similar views, and requires setting unsafe-inline keyword in style-src.

Could you please provide guidelines on how to correctly use Webix without having to set unsafe-inline or unsafe-eval keywords for scripts and styles in the CSP?

Thanks.
