[Bug] Cant find path between arrayAccess and controlStructure.condition #5718

Describe the bug
Trying to learn joern rules by working on an old ctf from HTB, namely dream diary 3.
Decompiled in Ghidra and exported to C.
Wrote a rule to find path from a local variable inside a do-while loop to the conditionOut of the loop.
No path is found.

To Reproduce
Steps to reproduce the behavior:

1. c2cpg diary3.c
2. joern cpg.bin
3. cpg.arrayAccess.subscript.reachableByFlows( cpg.controlStructure ).p
4. or cpg.arrayAccess.subscript.reachableByFlows( cpg.controlStructure.condition ).p

No flows found

Expected behavior
Since the variable is used inside the do-while loop I would expect a path to be found

Desktop (please complete the following information):
