Sorting items by columns in pages app does not work properly:

We can already see the problem on Magnolia demo author page -> pages app by clicking
on each column, for example Template or Title: The items seem to be
grouped by name but groups are not sorted properly.
Sometimes it is not even grouped by name...
However, it is not working properly and it is very inconvenient for end user...

I saw that bugs have been reported, and we are aware fixing that problem
could be very difficult, nevertheless we would like to know if you intend to fix this bug in the near future.

I thank you in advance for your reply.
