The result of opening multiple panes via ps1 script is unpredictable

[Rusinas]

This is a weird one.

I made a pretty simple PowerShell script to run my project.

$path = './Desktop/Code/projects'
$windowId = 'app'
$wtCommand = 'split-pane'

$command = "wt -M -w $windowId pwsh -NoExit -c 'cd $path/app/client && npm run dev' && " +
           "wt -M -w $windowId $wtCommand -V pwsh -NoExit -c 'cd $path/app/backend && air' && " +
           "wt -M -w $windowId $wtCommand -V pwsh -NoExit -c 'cd $path/app/admin && npm run dev' && " +
           "wt -M -w $windowId $wtCommand -H pwsh -NoExit -c 'cd $path/Auth/server && air' && " +
           "wt -M -w $windowId $wtCommand -V pwsh -NoExit -c 'cd $path/service_1 && air' && " +
           "wt -M -w $windowId $wtCommand -V pwsh -NoExit -c 'cd $path/service_2 && docker run -p 8090:8090 service_2:latest'"

Invoke-Expression $command

And it ALWAYS opens exactly two tabs, but sometimes it opens all the panes correctly, sometimes don't split the editor at all, running just random two apps. Really random behavior.

But if I change command to the new-tab instead of the split-pane, it will open all the 6 tabs every time just fine.

The terminal version is 1.19.10302.0. I've tried pre-release too, same there.
