The vertex tool dock now has a new checkbox for "Auto-open table", which is checked by default and retains the existing behavior.
If a user opts to uncheck this, then the vertex editor dock auto open/close behavior will be disabled, leaving the dock as regular QGIS dock which behaves the same as any other dock.
This is desirable in situations when:
If a user has opted out of the auto-open table behavior, then the dock can be closed and won't show immediately when switching to the vertex tool. The dock can then be re-opened either through the standard Views - Panels menu (or by right clicking a toolbar), OR through a new "Show Vertex Editor" action which has been added to the dropdown menu for the vertex editor toolbar button.
