The Book panel does not remember its size and location
The Book panel is the only panel in InDesign that doesn't remember its size and position when you close and re-open it.
Steps to reproduce:
- Create a new book (File > New > Book). The book panel is shown at the centre of the screen. No need to add documents to it.
- Move the panel to another location on the screen, and change its size in the usual way (click-drag on a corner of the panel).
- Save the book and close it.
- Re-open the book.
Expected behaviour: the book panel is opened at the same location and at the same size as when you closed it.
Actual behaviour: the book panel is opened at the centre of the screen at the size it was when you created it.
