IE11: Selection is lost when opening dropdowns or menu buttons or inserting tables

[Jakub Ś]

1. Select some text
2. Open dropdown or one of Color Menu Button (visible selection is gone)
3. Select any style or color from dropdown or menu buttons

Result: Selection is lost and cursor is blinking at the beginning of the content ^Apollo 11

UPDATES:

• Same happens when you try to insert table (or table inside table) - it gets inserted at the top of document.
• Same happens when you try to remove table with CKEditor context menu option.
• Even worse happens when you try to insert new column - selection is lost and JS error is thrown because of that.
