If one sus as a different user than the logged-in one, and starts Sublime Text from the command line as that other user, then copy operations will not use the logged-in user’s clipboard, making the copy functionality useless. Pasting does work though.
I consider this a bug since no other editor has this behavior, and it is annoying to have to define a different EDITOR depending on whether GUI user and CLI user match or not.
