Issue: Some unicode characters are displayed in the wrong color in the "Light+ V2 (Experimetal)" theme
Labels: bug,confirmation-pending,terminal-rendering

Type: <b>Bug</b>

Some unicode characters, like │ (U+2502) are displayed as white rather than black in the VS Code terminal when the theme is set to "Light+ V2 (Experimetal)"

This makes the rulers in a polars or ibis tables quite hard to see. The problem also effects the display of Julia PrettyTables.jl (which is the renderer used by DataFrames.jl and some other packages). There are likely more cases where vertical rulers are printed that aren't coming to my mind right now.

To reproduce, copy '│' into a terminal, press enter and switch between "Light+ V2 (Experimetal)" and any other theme. Or, open python and run
```
import polars as pl
pl.DataFrame({'a': [1,2,3], 'b': [3,4,5]})
```
or open Julia and run
```
using DataFrames
DataFrame(randn(5,5),:auto)
```
Note that the bug persists even if I start with `code --disable-extensions`.
