[qutebrowser] Weird website layout

[Erazem Kokot]

Hi,

I've been working on a school project, which involves modifying a
website that uses Javascript, Handlebars for the layout and an SQLite
database.
The website is running locally using nodejs.

Weirdly though, qutebrowser doesn't show the correct layout, rendering it like
this: https://imgbbb.com/images/2020/04/21/21-04-20_14-51-50.png, while the
correct layout should be like this:
https://imgbbb.com/images/2020/04/21/21-04-20_14-52-11.png
(displayed in Firefox Developer Edition).

I've moved the qutebrowser config directory elsewhere (so it used its
default settings).

Does anybody have any idea what could be the cause of this?

I can share the code if needed.

Kind regards,
