[UI] Potential incorrect placement of helper text

Hi

If I've interpreted this correctly, should the hint about 'item' be above the Value input box?

This is seen when editing a Markdown column type on a table.

Hey @ferret141 - it took me a minute to figure out the logic, but the tooltip is actually accurate in this particular instance. Specifically, you can only reference item in the Value input if you've previously set a Source.
