Make it clear required fields were not filled out in Contributor Sidebar
Ideally, the Save button on the contributor sidebar should be greyed-out when an idea has not been selected.
A few of our contributors got tripped up by this, they typed in the feedback, clicked the save button and got confused because nothing happened. They didn't realize that their feedback hadn't been submitted because they hadn't selected an idea.
