Display order not working for objects inside block entities

It seems that information of display order are lost when I make several objects into a block.

Attached jpeg graphic is showing an example.

Objects on right side is the display order which I intend, that is, from top to bottom, yellow line -> solid hatch -> red line. On the left showing these entities turned into a block that lost intended display order.

The order will not be changed even if I enter “EDITCOMPONENT” mode and alter display order with “DISPLAYORDER” command. The display order doesn’t seem to be reflected even after using “REFRESHALL” command.

Is there any way to alter the display order of block entities? Or is this a bug?
