Resizing panes only resizes multiple lines at a time

Issue description

When resizing panes vertically, Zellij appears to resize by multiple lines at a time (5 in my case, though this may depend on overall window size). This leaves me with a choice of a pane that is either too short or too tall.

IMO, Zellij should resize by one cell at a time; if I want to resize by five lines, I can press the arrow key five times, but I cannot press it one-fifth of a time with the current behaviour :)

Minimal reproduction

Install the repro setup.
Start zellij.
Create a second pane with ⌃p n
Enter resize mode with ⌃n
Press the up arrow key

config.kdl

plugins {
    tab-bar location="zellij:tab-bar"
    status-bar location="zellij:status-bar"
}

default_layout "demo"

layouts/demo.kdl

layout {
    pane size=1 borderless=true {
        plugin location="tab-bar"
    }
    pane split_direction="vertical"
    pane size=2 borderless=true {
        plugin location="status-bar"
    }
}
