using "vscode-remote://attached-container" url from wsl erroneously converts slashes to backslashes

[Spongman]

Type: Bug

• install dev containers extension
• install remote-wsl extension
• connect vscode to wsl guest
• create a container with id $CONTAINER_ID
• in wsl guest execute:

    code --file-uri vscode-remote://attached-container+$(printf "$CONTAINER_ID" | xxd -p -1000)/server/ui

EXPECTED: windows vscode to open, connect to container, and open DIRECTORY server/ui

RESULT: windows vscode opens, connects to container, but opens new FILE named \server\ui

somebody somewhere is converting / to \ and it's breaking it.
