enable_cursor_positioning doesn't seem to take any effect

[shumvgolove]

Hello there!

The docs mention that:

enable_cursor_positioning enable fetching the cursor position in bash and zsh to allow automatic hiding of leading newlines when at the top of the shell

Unfortunately, enabling that option doesn't seem to take any effect: extra newline is still printed. I've read the following issues with the similar problem:

• newline in zsh not cleared on Ctrl+L #5703
• An extra line between the prompt and the top of the terminal #5732

...but I'm a little confused: is it a limitation of zsh as pointed in #5703, or does enable_cursor_positioning suppose to fix the issue? Thanks in advance.

Environment

• os: Linux
• zsh: 5.9
• oh-my-posh: v24.17.1

Steps to reproduce

1. Create the following config:

   nvim 1.toml

   version = 3
   shell_integration = true
   enable_cursor_positioning = true
   final_space = true
   
   [[blocks]]
     type = 'prompt'
     alignment = 'left'
     newline = true
   
     [[blocks.segments]]
       template = '{{ .Path }}'
       foreground = 'yellow'
       background = 'transparent'
       type = 'path'
       style = 'plain'
   
       [blocks.segments.properties]
         cache_duration = 'none'
         style = 'full'
   
   [[blocks]]
     type = 'prompt'
     alignment = 'left'
     newline = true
   
     [[blocks.segments]]
       template = '❯'
       background = 'transparent'
       type = 'text'
       style = 'plain'
       foreground_templates = ['{{if eq .Code 0}}green{{else}}red{{end}}']
   
       [blocks.segments.properties]
         cache_duration = 'none'

2. Launch clean zsh:

   zsh -dfi

3. Init oh-my-posh:

   eval "$(ohmyposh init zsh --config 1.toml)"

4. Clear the screen once with Ctrl+L.

5. Execute anything (e.g. whoami like in an original issue).

6. Clear the screen again with Ctrl+L and observe that extra line is added even with enable_cursor_positioning = true.

Okay, adding the following to .zshrc:

bindkey -s '^L' 'clear^M'

solves the issue for me. Still, I'm curious if enable_cursor_positioning should solve this on it's own.
