In XWD9P, I can create a box and in its Placeholder Body add something.
If I Select it when the Web/Link properties dialog window is closed, you get the Widget Edit popup. When you click Edit, the Web Properties dialog correctly opens to the Placeholder tab.
If I add something to the Placeholder Head of a box, the same operation switches to the Rectangle Tool.
The same would happen for the Shape Tool and the Text Tool if the text is grouped; all switch to their last invoked Tool: e.g., 3D but not Bevel.
