State of WFs in Isolation-Group-Queue

Dear OD users,
I have a question regarding Isolation-Groups in OD: Let’s assume WFs A an B are in the same Isolation-Group, A is executed first and B is currently waiting in the queue. What is the state of B during this time (INITIAL, RUNNING, or maybe still the state from its last run?)?
Thank you very much in advance!

It stays in state Initial while it is waiting.

(Also I noticed that it seems to never switch to running at all, might be a bug)
