geometry swallows output without trailing \n

Command output lacking a terminating newline gets overwritten by the prompt

Screenshot: default zsh prompt first, then geometry

The default zsh prompt adds the newline when it's missing (marked by the inverted % ), but unfortunately this not only does not work with geometry, it also "swallows" the output, overwriting it with the prompt.
The output does show up very briefly, but the prompt overwrites it.

I also tested it with GEOMETRY_PROMPT=(geometry_newline) but that does not help, it overwrites the output with an empty line.

To Reproduce
echo -n "Test123 :^)"

Tested on
Archlinux, with Alacritty and xfce4-terminal

I looked into this issue some more and it seems to be an issue with marlonrichert/zsh-snap and its znap prompt. It does not occur when I source geometry.zsh normally.
Sorry about that!

In my case this was due to having unsetopt prompt_s in my configuration.
