it seems like the
display:flex; style is not applied to the right component in the builder editor.
I’m dropping a basic Columns component, and adding some text in each column.
In the generated code, their is a parent component which has the display: flex style applied, then this parent has one child with
builder-columns class, and that child has the actual columns as children.
The result is that all the content appears in the first column.
I am using Nuxt with the vue3 sdk. And it seems to be the same issue as this unresolved post.
