As I reported the two mentioned bugs, I have to say: I don't like it too
Here is another one which affects portrait mode:
https://bugs.maemo.org/show_bug.cgi?id=4617

Well basically this mean that the usage of the portrait mode is not recommended and if you (as developer) want to use it, you'll have to write (mostly) a complete new UI. Then if you still want to maintain the Diablo version you have to maintain 3 more or less different UIs:
Diablo / Fremantle landscape / Fremantle portrait.

That's not fun at all and I can see how developers will drop support for Diablo quite quickly...

Not UI related, but another thing that wont get fixed in Fremantle:
