LESS='--clear-screen' makes bat go wrong

[QuarticCat]

$ export LESS='--clear-screen'
$ echo 1 | bat

You can see that bat outputs extra ~ lines.

But if I set

$ export BAT_PAGER='less --quit-if-one-screen --RAW-CONTROL-CHARS --no-init -+clear-screen'

I will get

$ echo 1 | bat
There is no -l option ("less --help" for help)
Press RETURN to continue

Solved. It turns out that -+ only works for short flags. So it should be -+c instead of -+clear-screen. But I encounter a new problem.

My configurations are

export LESS='--quit-if-one-screen --RAW-CONTROL-CHARS --chop-long-lines --clear-screen'

export BAT_PAGER='less --quit-if-one-screen --RAW-CONTROL-CHARS --no-init -+c'

export MANPAGER='sh -c "col -bx | bat -pl man --theme=Monokai\ Extended"'
export MANROFFOPT='-c'

Then when using man less, I find that I cannot scroll the page by mouse wheels.
