I have one Epic "EPIC1"
EPIC1 has the Story linked to it "STORY1"
Now, when I am raising a bug and choosing "STORY1" under "Issues" field then the "Epic Link" field should also automatically be filled in based on what is chosen as epic link in "STORY1"
So, here while raising a bug, the epic link should be automatically be chosen/selected as "EPIC1" since I have selected "Issues" field value as "STORY1"
