WAD... lol
Seriously though, anything that isn't working to the expectations of the user can be considered a bug/defect. Sometimes it is just semantics differences between how people are using a word. To me, issue, bug, and defect all mean the same thing. Bug is typically seen in a harsher light than defect. But they essentially mean the same thing, something isn't working as expected.
The original poster is correct and I ran into this issue without realizing it. Good find @Trug and great repro steps! It really clears up what I was seeing and didn't realize the work around.
