man page doesn't get colorized if the default theme's changed #2115
Description
Describe the bug you encountered:
I tried playing with multiple options, but as soon as I change the default theme to anything else, colorization on man pages break.
I tried setting theme to ansi, base16, base16-256, OneHalfDark, and 1337. I also set --color=always, but that didn't help either even though I explicitly specify the language as man while piping into bat.
This can be reproduced by invoking bat on bat's help itself: bat --help | bat -l man. Highlighting works with the default theme, but not with others -- only a few words get highlighted.
...
What did you expect to happen instead?
Syntax highlighting on the man page just as it functions with the default theme.
...
How did you install bat?
I used Scoop to install bat.
bat version and environment
I use PowerShell 7.2.1 that supports Unicode by default and Windows Terminal that has xterm-256 terminal capabilities.
This the output on running bat --help | bat -l man --diagnostic:

# This is `bat`s configuration file. Each line either contains a comment or

# Enable this to use italic text on the terminal. This is not supported on all

--italic-text=always
# Uncomment the following line to disable automatic paging:
#--paging=never
# Uncomment the following line if you are using less version >= 551 and want to
# enable mouse scrolling support in `bat` when running inside tmux. This might
# disable text selection, unless you press shift.

# Syntax mappings: map a certain filename pattern to a language.
# Example 1: use the C++ syntax for Arduino .ino files

#--map-syntax ".ignore:Git Ignore"
