component definition buggy if argument defined without type

[amitu]

-- component footer:
ds: design-system

-- footer.ds.section-column:
ds: $footer.ds

-- ftd.image:
src: https://www.fifthtry.com/-/fifthtry.com/assets/images/logo-ycom-dark.svg

-- end: footer.ds.section-column

-- end: footer

Leads to error in -- end: footer.ds.section-column line.
