Multiple Assignment results in no output

[colinjbrown]

When assigning to multiple elements instead of choosing one or the other part or both all parts of the assignment is ignored and instead nothing is output.

To Reproduce:

a,b = c,d = 3,4

Interesting this issue still exists in the lab extension

I think there is a question about what should happen here. In ipykernel in last_expr_or_assign ast_node_interactivity mode, no output is shown for a statement like b = c = 12. For us, showing no output seems incorrect. We could show just b or both b and c as outputs, but what would be the point of the second option? I would argue that having just b or in the case of the example above, a and b, would be the correct outputs.
