Steps to reproduce

wt -w 0 split-pane
wt -w 0 split-pane -H
# Afterwards somehow new tabs are created instead of splitting the current one
wt -w 0 split-pane

Expected Behavior

wt -w 0 split-pane and wt -w 0 split-pane -H should split the current window instead of creating a new splitted tab.

Actual Behavior

wt -w 0 split-tab always opens a new Tab, which is than splitted instead of splitting the current tab. Somehow this happened after switching one time to wt -w 0 split-tab -H. Afterwards always a new tab is created with and without -H

At first I was expecting that the upgrade from 1.22.12111.0 caused this issue. But on another Windows 11 PC with 1.23.12371.0 it was working fine until I used -H again
