Issue summary

Actual behavior

Terminal is paused after first command

Steps to reproduce

The problem is when command is sync. If the command is animated or async it works fine.

var term = $('body').terminal(function(command) {
    const cmd = $.terminal.parse_command(command);
    if (cmd.name === 'echo') {
        this.echo(cmd.rest);
    }
});
term..exec(['echo 111111', 'echo 222222', 'echo 33333'], {typing: true, delay: 50});
