bug: bat does not display colors correctly

[massivebird]

Colors are not displayed correctly when invoking bat with ctrl+shift+g (Kitty's pager keybind).

Piping output directly to bat displays characters correctly, but without any color data.

Steps to reproduce

$ cd <repo>
$ git log
<ctrl+shift+g> # invokes kitty's pager
# output:
