[BUG] Modifying console theme has no effect on traceback

[AaronBeaudoin]

Description

When a traceback is printed to a console which has a modified theme applied to it, the theme's styles are not used when printing the traceback.

Reproduction

In this example, I expect the border of the traceback to be blue and the "tag" name and contents to be black. Instead, the defaults continue to be used. Removing the theme="bw" does not produce the expect result either.

from rich.console import Console
from rich.theme import Theme

console = Console(theme=Theme({
    "repr.tag_name": "bold black",
    "repr.tag_contents": "black",
    "traceback.border": "blue",
    "traceback.border.syntax_error": "blue"}))

try: raise Exception
except Exception: console.print_exception(theme="bw", show_locals=True)

Platform

MacOS, Terminal App (Happens in VS Code too.)
