Run Textual app inside Textual textual-terminal looks strange

[mitosch]

I don't know, if it is a use case, but running bash inside textual-terminal and open another (e.g. the example again) Textual app, it looks strange: like black-white, scrollbar is misplaced.

Rich is reporting, that brightwhite is not a valid color, which should not be the case. Isn't Textual using Rich colors?

Could be a general color detection problem.

Step to reproduce:

• Run the example
• Inside Terminal 2 (bash) navigate to the textual-terminal dir
• Run the example inside Terminal 2 again
