Is it possible to restrict summary to one line?

[BlueManCZ]

Hello,
is there a way to configure Dunst so that the notification summary stays on a single line? Currently, when the summary is long, it wraps over multiple lines and, with specific height set, takes up the entire notification space, resulting in this appearance:

notify-send "Lorem ipsum notification lorem ipsum notification lorem ipsum notification" "This notification is for testing purposes"

I'm trying to achieve something similar to this:

Even just simply cut out without ellipsis would be fine.

I went through the dunst(5) and Pango markdown but didn't find anything useful or similar to HTML's nowrap attribute or CSS's white-space.

Hello, I think that currently the ellipsize property is applied to the whole layout, so to do what you want we would need to modify and provide an extra ellipsize property.
I like this idea, so we may add it in the future
