Note: Even though vscode exposes var(--vscode-terminalCursor-foreground) it does not render in front of a color that isn't var(--vscode-terminal-background), and it turns out a lot of themes don't even define some/any of these terminal color variables. Very odd behavior, so try changing themes/color variables if you don't see the caret.
