Union of pointers is not shown correctly in Decompiler

See original GitHub issue

Describe the bug When creating structure with union of pointers to another structure on disasembly it appears to be shown incorectly in disassembler.

Screenshots Main Structure Union with pointers to structures Dissassembly

Expected behavior When we have union in struture what is union of pointers to different structures i expect it to:

be able to pick member of union
show code in dissasembly view with actual union field and then eventually offset it. In this case we should get something like this if (pUnit->eUnitType == UNITTYPE_Object) { *(D2ShrinesTxt **)(pUnit->pUnitData->pDataObject[8]) = pShrinesTxt; return; } instead of code shown above on screenshot.
after rightclicking we should be able to select what union member we want to use.

Environment (please complete the following information):

OS: Windows 10
Java Version: jdk-11.0.2
Ghidra Version: 9.0 (first public version)

Having the ability to define unions at all seems kind of useless without this.

It’s been almost 2 years and this issue is still not resolved. Maybe we can have some more attention on this topic? Or at least official statement it will/will not be implemented. We are in this void for quite some time…
