Debug config name overflows dropdown in a Codespace

Interesting, in Electron, there is a default style applied to all select from the builtin "user agent stylesheet" that sets box-sizing: border-box. In the browser that doesn't exist 🤔

No, that's wrong, there's a codespaces stylesheet breaking this.

@osortega I remember having issues like this in the past, do you know anything about this? Is codespaces supposed to be adding extra stylesheets to the vscode workbench?

[osortega]

@roblourens yeah we add a few things for rendering the workbench correctly.
Looks like the property messing things up is box-sizing: content-box; which based on the comment, seems that it was needed for VS Code itself.

I removed the attribute and everything seems ok, so I'll remove it.
