Handling of linked docs. in html documentation

[Jan van Mastbergen]

Some use cases in my model have a linked document, some don't. If I generate html documentation and click a use case in the diagram, behaviour is different depending on whether item has a linked document or not.
(a) If it does not, item metadata is shown including notes, links etc. as usual.
(b) If it does, only content of the linked document is shown. To see the metadata I need to select the use case in the tree display (which also shows the linked doc. btw).

How can I get the behaviour of (b) to revert to (a)?

TIA, Jan
