Task created in the To Do application is not autosaved if I miss to press Enter or click Add

When I type out a task in the To Do application and if I forget to press enter or click add or I press tab like I used to do in the Tasks application in Outlook (which doesn't save the respective task). Then if I toggle to another group of tasks whatever I typed there is lost if I don't press enter or click add.

If something is typed in this Add a task field (refer the screenshot given below), and then you toggle somewhere else you shouldn't lose it, but it should automatically add whatever is entered in that field to the respective list.
