python.terminal.executeInFileDir doesn't work if file is on another drive from working directory

Environment data

• VS Code version: 1.51.1

• OS and version: Windows 10.0.19042
• Python version (& distribution if applicable, e.g. Anaconda): Anaconda Python 3.6.12 64-bit
• Type of virtual environment used (N/A | venv | virtualenv | conda | …): conda
• Relevant/affected Python packages and their versions: NA
• Relevant/affected Python-related VS Code extensions and their versions: NA

Expected behaviour

Expect that if the file directory is on a different drive to the working directory and “python.terminal.executeInFileDir” is set to true, that the terminal will change drive, then change directory, then run python file

Actual behaviour

Terminal opens, changes directory and then runs python file

Steps to reproduce:

1. Have python.terminal.executeInFileDir = True
2. Open python file on drive other than working directory
3. Run python file in terminal

Terminal will open, run the ‘cd FileDir’ command but not change drive, and then run the python file

if ((!wkspace || fileDirPath !== wkspace.uri.fsPath) && fileDirPath.length > 0) { await this.getTerminalService(file).sendText(`cd ${fileDirPath.fileToCommandArgument()}`); }

I’d like to start solving this issue

I see an issue here, running a file in a different drive works. but then when you run a file in the same dir as the workspace, it does not work. It does not restore the directory.

After step 5 of verification, run a python file from the workspace. it sends a cd but not a drive change.
