Bug Report

App Version: v2.0.13

Platform: Linux

Steps to Reproduce:

1. Click on an existing todo with Priority A.
2. Click on the priority field.
3. Press "M" key (or any letter key).
4. See that the "M" option is selected, sort of.
5. Click the "Update" button. See that the Priority dropdown goes away (as expected).
6. Bug: See that the Priority remains A.

Expected Behavior:
I'd expect the Priority to switch to "M", because I pressed M on the keyboard.

Actual Behavior:
The Priority stays as the original value ("A").
