Saving an entry with no title does nothing, with no explanation

The create form (quick add / bottom sheet) requires a title. If you type only a description and leave the title blank, tapping save does nothing at all - the sheet stays open, no error text, no snackbar, no hint that a title is what's missing. The submit button isn't disabled either, so there's no signal before you tap. The description text isn't actually lost (it's kept as a draft and restored next time), but there's no way for the user to know that. Expected: either disable the save button while the title is empty, or show a short message explaining a title is needed. Worth noting the app is inconsistent here - on the entry detail screen you can clear a title to empty and it saves fine, and in prompts a blank title deletes the entry. Reported on Android 1.74.2.
