Without this in place, the following assert
would be triggered when closing the dialog:
soffice.bin: /home/michi/development/git/libreoffice/include/vcl/vclptr.hxx:134: VclPtr<SfxAbstractTabDialog>::~VclPtr() [reference_type = SfxAbstractTabDialog]: Assertion `(!m_rInnerRef.get() || m_rInnerRef->isDisposed() || m_rInnerRef->getRefCount() > 1) && "someone forgot to call dispose()"' failed.
Steps to reproduce:
* start Draw
* make sure the "Text" toolbar is enabled in "View" -> "Toolbars" -> "Text"
* in that "Text" toolbar, select the "Callouts" shape and insert it into the document
* right-click on the newly inserted shape to open the context menu
* activate the "Position and Size" menu entry to open the dialog
* press the "OK" button to close the dialog again
