[FIX] web_editor: put the snippet editor UI at the correct DOM position

Commit https://github.com/odoo/odoo/commit/4f27e52cabb77b8b1a9637a11185ddf882adc9af
had to instantiate the snippet editor UI differently but the hack broke
the position of the oe_manipulator which is supposed to be at the top
left of the editable zone.
