Not working with custom keyboard keymaps

Lapce Version

0.3.1 - flatpak

System information

PopOS 22.04 - i3wm

Describe the bug

I have binded Capslock to Escape in my system with:
setxkbmap -layout 'us,ir' -option 'grp:alt_shift_toggle' -option 'caps:escape'

so when I'm using neovim(my primary editor) I just use capslock for escape.

now I enabled vim mode in lapce, and escape key works but capslock doesn't register as escape.

I don't know what is wrong but if someone has a clue, tell me what to do for more information.
