Listview sort-order not working when adding textbox search widget (7.11)

I have a similar situation as I've got it worked-around but want to understand .... In mx 7.11 i have a listview sorted on sequence number. I added the textbox search now the sorting didn't work anymore. As a workaround: I added the dropdown sort widget, to add the default sorting. Now it works again. I don't want to show the customer a widget that has no meaning. (only one sort order). So i added the style "visibility: hidden;" to the container with the dropdown sort.  So now it looks as designed, but I cannot understand why the listview sort cannot be applied out of the box...

Still in 7.23.2 this bug isn't solved and I didn't read anything about this in release notes if 7.23.3 and 7.23.4 This is very frustrated. The workaround described here above doesn't work always.

Update, with 7.23.4 still not working.
