column overflows when wrapped in el

[opsb]

The big picture of what I'm trying to do

Wrap a column in another element (in my actual app it's just part of a complex layout)

What I did

See https://ellie-app.com/4dNxnZYt7G2a1/2

In the ellie you can see a column (body) in 4 different scenarios (all with height <| fill 1)

1. Not wrapped
2. Wrapped in an el
3. Wrapped in a column
4. Wrapped in a row

What I Expected To Happen

(2) should look the same as (1)/(3)/(4)

What Actually Happened

(2) overflows parent into the footer at the bottom of the view
