netlify dev --dir not working with dev command configured

[cco3]

> mkdir dist
> echo -e '[dev]\n  command = "mkdir dist"' > netlify.toml
> netlify dev --dir dist
◈ Netlify Dev ◈
◈ Using simple static server because --dir flag was specified
◈ Running static server from "mydir/dist"
◈ "command" option cannot be used in conjunction with "dir" flag which is used to run a static server

netlify-cli: 2.52.0

@cco3 Can you please explain what you think correct behavior should be. It would be helpful if you can fillout the issue template, it helps reduce the back-and-forth questioning.
--dir flag is used to run a static server while the purpose of command option is to run an app server.
If you want to run netlify dev in a specific directory with a command, you can specify publish and command options in netlify.toml [dev] section.

Bug

- What is the current behavior?

--dir option does not work if a dev build command is configured.

- If the current behavior is a bug, please provide the steps to reproduce.

Steps provided above.

- What is the expected behavior?

I can use the --dir option even if my project is configured to build when running dev without the dir option.

This was the behavior of previous versions of netlify-cli, like 2.46.0 and earlier.

Configuring defaults in a project should not make explicit invocations fail.

@RaeesBhatti I've offered a justification above for classifying this as a bug. Would you be willing to give this a second consideration?

[RaeesBhatti]

@cco3 I see the problem. It is indeed a bug. Thank you!

[RaeesBhatti]

@cco3 Can you please try out #936 and let me know if that works for you!

[cco3]

It works, thanks!
