Short answer: No, they are not bugs.
The rule is:
In any mixed-type operation between two objects of the same fundamental
"kind" (i.e. integer, float, complex) arrays always have precedence over
"scalars" (where a 0-d array is considered a scalar in this context).
It's a rule whose reason has a long history.
