TinyMCE popups break globally on 3.1.8

[Tangdongle]

When adding a new config and setting on an HTMLEditorField, popups cease to function on the default HTMLEditorField. This includes, Link, HTML Editor, Special Character Editor and the Table button.

So far I can't seem to reproduce this. Can you give me some example code that's not working for you?

@Tangdongle - it might be because the code I provided you with changes the body class of the editor, perhaps try removing the line $footerField->setBodyClass('banner-content'); from the configuration and see if that works?

[Tangdongle]

Using this config:
$simpleConfig = HTMLEditorConfig::get('simple');
$simpleConfig->setButtonsForLine(1, array(
'bold',
'underline',
'link',
'unlink',
));
$simpleConfig->setButtonsForLine(2, array());

And with this set on the editor:
$simpleHTMLEditor = new HTMLEditorField('c1', '');
$simpleHTMLEditor->setEditorConfig('simple');

And with a 'simple' HTMLEditorField and SS' default Content HTMLEditorField on the same tab.
Edit: It seems it only occurs when you refresh the CMS, yet functions fine when you move between pages.

A bit of experimenting tells me the problem seems to be HTMLEditorConfig::get('simple');. Just having that in there causes error even if there's no associated field.

I'll look into it further but as a quick fix this seems to work:

$simpleConfig =  CustomHtmlEditorConfig::copy('simple', 'cms');

I suspect the problem is that initialising a blank config (even with CustomHtmlEditorConfig::copy('simple', 'simple'); makes it miss some required setting that's in the cms config.
