Fred preview issues

Support Extras
1

When previewing a page in Fred, I’m experiencing some issues:

  1. Everything that has its height set to 100% in the css is much higher than it should be. The reason seems to be the fred–content-preview class that wraps everything.

  2. Some positioning is off, see for example these Font Awesome icons: https://snipboard.io/PJLxwf.jpg

The issues are the same in all views (mobile, tablet, auto).

Is there any way to correct this?
