Carousel pagination arrows don't complete the action on keyboard navigation

[samelhusseini]

Keyboarding space / enter on the carousel left and right arrows doesn't complete the action.

Repro: On the homescreen tab to the left or right arrow buttons, and hit space / enter. Nothing happens

Expected it should do the same as a click, and move the carousel over to the next page.

This is a PXT issue.
