Bugfix
(User-visible)
Some tabs are controlled via the toolrow. Since the comments of the implementation class written in the code are used as tooltips for CommandHandler, the tooltips for these tabs are nonsense:
The <i>class default tab switch veto command</i> is a <i>tab switch veto command</i> whose <i>tab switch veto listener</i> is a <i>default tab switch veto listener</i> that opens the dialog box in the window where the command is executed.
Improvement
The tooltip of the tab to be displayed is used, otherwise no tooltip (then the label is automatically displayed in the tooltip).
Test
In the Modern theme in the toolrow, the commands that change the tab show the name of the tab or a description of the tab in the tooltip.
