Research direction
Start by reproducing the issue in the VSCodeVim extension on macOS with VS Code 1.45.0: enable the Vim plugin, hold Option/Alt, and drag on the trackpad. Compare the cursor and selection behavior with the plugin disabled; done means Option-drag produces stable block selection while the plugin is enabled.
