Limiting improves readability on wide monitors.

The immediate update of the settings is done by just exposing settings
as properties and then setting the settings as a context property.

In the future we should probably add a gradient when clipped...

Can't do it for QtWidgets code. We need to fully transition, before we
can fully switch over probably.

This currently assumes the event, that is replied to, is already
fetched. If it isn't, it will render an empty reply. In the future we
should fetch replies before rendering them.

Thanks to red_sky for the feedback!
