Two RTE toolbars are displayed when opening secondary editor while inline editing

Description

When having an inline editable text that is also editable via the RichtTextEditor in the inspector, opening the secondary editor will show an additional toolbar to the one of the inline editable. This is very confusing as the inline editor buttons are also active.

Steps to Reproduce

Add the following f.e. to a Neos.NodeTypes:Text content elements definition:

inspector:
   editor: Neos.Neos/Inspector/Editors/RichTextEditor

Expected behavior

Only one toolbar is visible/active

Actual behavior

Two toolbars are displayed:

Affected Versions

Neos: 7.3+

UI: 7.3+

Every since the RichTextEditor was added.

Additionally it's quite confusing that they don't share their formatting options, therefore most formats not working in the one or the other editor. Would you save a change then, it would loose the missing formats.
