Problem / Steps to reproduce

Environment

pwsh version: PowerShell 7.5.4
Operating system: Windows 10.0.26200
Terminal emulator: Windows Terminal Version: 1.23.20211.0
Neovim vesrion: v0.11.6

I found some weird behavior when using become:nvim {} and --height. When I run this command:

fzf --bind "enter:become:vim {}" --height='100%'

Everything works as expected. Neovim opens the selected file in normal mode.

However, if I set --height to anything other than 100%, Neovim opens in operator pending mode and behaves as if I pressed y to yank. Navigating up or down then triggers a yank instead of just moving the cursor.

In the nvim cmdline, y can be seen as if I typed it in normal mode. It also outputs no previous search which is a message from leap.nvim that appears if ; is pressed without a previous search. Somehow, keystrokes are being sent to neovim after opening without me doing anything. If I use nvim --clean then the leap message is not displayed but the y keystroke is still being sent.

Does anyone know what could be causing this? This behavior only occurs in PowerShell, in zsh on Mac or WSL2 everything works fine.
