WezTerm: 'inverted' style with bg incorrectly sets bg to black

[ShojiHorikawa]

Bug Report

Current Behavior

When using the inverted style with bg:none in WezTerm, the background color is incorrectly set to black instead of remaining transparent.

Expected Behavior

The background should remain transparent when using bg:none with the inverted style.

Possible Solution

No specific solution has been identified yet, but it may involve adjusting how WezTerm handles the inverted style with transparent backgrounds.

Environment

Starship version: 1.22.1

Terminal emulator:
WezTerm: 20250301-123420-7d0bff06
vscode: 1.98.2
iTerm2: 3.5.11

OS ProductVersion: 14.7.1

Starship prints the ANSI escape for inverted verbatim, and the way it is handled is left to the terminal application. That said, it might be useful to add this to the list of warnings regarding non-universal support for some style directives in the advanced config section of the documentation.
