Dataframe selecting columns does not apply until adding another transformation

[hkrutzer]

Describe the bug

• Go to https://docs.marimo.io/api/inputs/dataframe.html
• Add a Select Columns transform
• Select two columns
• Observe no columns are selected
• You must add another transformation before columns are selected

There is also some automatic scrolling going on.
