Watch tasks can now be reconnected to on window reload. Verify that this does not happen by default.

Then verify that it works via task.experimental.reconnection

Note that the setting will only take effect for terminals you create in the future.

Good examples are the VS Code - Build task and xterm.js watch task. Both can be activated via the command palette or Ctrl/Cmd+Shift+B.

Make sure that you can kill the terminals and run the task again without issues, that the problems update, and anything else you can think of

Known issues:

• status doesn't update until you change a file and save it Task statuses and problems don't restore after reload #155246

Thanks, it works great.

After using external terminal for build/watch VS Code for 6 years, finally I don't have to use it anymore since the combination of daemon tasks and task restore covers it well (once #156294 fixed). Kudos to @meganrogge @Tyriar @joaomoreno !
