"Post something about crop" is not related to crop

I wrote a post but it wasn't about the beans, even though I started from the beans page

Reproduce steps:
Visit crop
Post something
Complain... About beans I guess
Save
View crop

Expected: my bean complaints were automatically prefilled with a crop link or association

Actual: nothing
