Relative route for "translate"

[kschutt]

Hello,

I noticed our app would stall when attempting to translate the selected recurrence into a summary string. Upon further investigation we noticed that the route below was receiving a 404:

https://www.domain.com/recurring_select/translate

However, our application is hosted at https://www.domain.com/folder

Therefore, the above route will have a 404 because the correct route should be at: https://www.domain.com/folder/recurring_select/translate

~~As of yet, I haven't been able to attempt a patch.~~

Thanks
