Jump word (option+arrow) navigation broken on mac

[jediahkatz]

My ability to navigate the VSCode/Cursor terminal with Option+Left/Right has been broken, possibly due to 4154623. Now it just types C and D characters instead of jumping. cc @Tyriar

This is super frustrating! A fix would be very much appreciated.

@jediahkatz I forgot which version of VS Code this landed in but it's controlled by built-in keybindings in VS Code now: https://github.com/microsoft/vscode/blob/df79a9c8e26d9d0d89b7f895843a53bc0519d746/src/vs/workbench/contrib/terminalContrib/sendSequence/browser/terminal.sendSequence.contribution.ts#L160-L179 - you left out the VS Code version, it's expected to not work in xterm.js
