PLUGINS: Uncaught Error: TOOLTIP: Option "container" provided type "undefined" but expected type "(string|element|boolean)".

steps to reproduce

1. Include summernote
2. Include plugin: specialchars
3. Add specialchars to toolbar

browser version and os version and summernote version

OS: OSX High Sierra Browser: Chrome 64.0.3282.186 (Official Build) (64-bit) Summernote: 0.8.10 (bs4)

When attempting to use the specialchars plugin, I get the error in the Issue title, and the button doesn’t render. Looking at the code, it appears that this plugin (and the others included) is calling ui.button incorrectly. Changing the block at line 67 to read

context.memo('button.specialchars', function() {
    return ui.button(
        $,
        {
            container: options.container,
            contents: '<i class="fa fa-font fa-flip-vertical">',
            tooltip: lang.specialChar.specialChar,
            click: function() {
                self.show();
            }
        }
    ).render();
});

After this, the plugin appears to work, but does provide another error: No method named "destroy". Changing (after the above changes) line 301 to read

self.$dialog.find('button').tooltip('hide');

appears to resolve this as well.

The reasons I don’t simply submit a pull request are that

• I don’t have a tremendous understanding of this repo, as I just started using it
• I don’t know how to unit-test javascript
• I can’t guarantee that nothing else breaks

var button = ui.button({
                                contents: '<i class="fa fa-child"/> Hello',
                                container: false,  //add option
                                tooltip: 'hello',
                                click: function () {
                                    // invoke insertText method with 'hello' on editor module.
                                    context.invoke('editor.insertText', 'hello');
                                }
                            });

I had the same problem. Adding container: false to the object for ui.button() fixed it.
