Patch restore lead trail space bg color (#10351)

Browse Source 
```nu
 $env.config.color_config.leading_trailing_space_bg = { bg: 'white' }; [[a b, 'c   ']; ['  1  ' '    2' '3    '] ['  4  ' "hello   \n  world  " ['  1  ' 2 [1 '  2  ' 3]]]] | table --expand
```

ref: #2794
close: #10317

note: test are not actually make scenes cause `nu!` strips colors.
(Ideally it would need a flag to not do so)
note: It does does does ... slower down quite a bit rendering... (

PS: Maybe it's better being a flag to `table` rather then a
configuration option?
PS: I am not sure why the logic was removed in a first place
