Tool bar will be scrolled out of frame

[kikouousya]

The toolbar of this component leaves the view as it scrolls when the content is too long and requires scrolling.

• Adding a position: sticky style to the customToolbarButton
• Hiding the original toolbar and adding a custom one above it. when click on my toolbar, the editor's on focus out will be triggered, and there is no option to disable it.

Code here, if you need more info, I will provide.
