Optional ReadonlycontainerWhere the menu is appended. Must be a positioned ancestor of the editing surface, or share its offset parent: the menu is placed absolutely within it. Defaults to the surface's own parent.
Optional ReadonlygapGap between the selection and the bubble, in px. Defaults to 8.
Optional ReadonlyshouldWhether to show at all, for hosts with their own rule. The default shows for any non-empty selection in an editable surface whose block takes marks, which is to say, never over a code block, where bolding text would be meaningless.
Optional ReadonlytoolbarPassed straight to the toolbar inside the bubble. Defaults to the six
inline actions below; pass items or groupNames for something else.
The classic bubble: the handful of things you want to do to text you have just selected, put where you are already looking instead of at the top of the window.
It never takes focus: every control cancels its own
mousedown, because the selection it acts on is exactly what a click would otherwise destroy.
