Thread:Extension talk:WYSIWYG/IE11 with MW 1.22.0 + WYSIWYG extension: numbered and bulleted list empties document with save/reply

In IE11, by pressing F12 DOM window opens. On "Emulation" -screen setting "Document mode" is set to "7 (default). If I change this to any value abowe 7 (8..10 or Edge), edited page with numbered and bulleted list can be saved succesfully. Only problem is that this setting does not stay in effect when page is re-edited and saved. Is it possible to change type of document for wysiwyg editor on server side somehow?
