Characters repeating during input in Android App

### Expected
Normal input of characters into list item.

### Observed
When char is inputted directly after a number, that number is first repeated and then the expected char is added automatically at point of input.

The input gets even funkier if you have multiple letter-number combos in the same string. This however does not happen if a letter is typed first, followed by a number.

### Reproduced
1. Open app on android (A71 5G model)
2. Go to any list, type number then any letter

Case 1: 44h
Case 2: 44xgg444xgg4y. 55h

### Where did you see the bug

- System Make: Galaxy
- System Model: A71 5G
- OS: Android
- Simplenote app version: 2.26 (155)

Reproduce the issue in the Android app on a Galaxy A71 5G by opening a list item and typing a number followed by a letter, including the reported sequences 44h and 44xgg444xgg4y. Trace the list-item input handling; done means characters are entered once and normally for both number-first and letter-first sequences.
