Spacebar Double-Tap Issue: Unintended Comma Replacement

[MikeStirner]

Thumb-Key Version
2.6.1

Describe the bug
The Thumb-Key program has a unique issue where double-tapping the spacebar results in the first space being replaced with a comma. This behavior is consistent and works as intended when spaces are created through normal typing. However, the issue arises in a specific scenario. If the cursor is manually moved on an Android phone by tapping on the screen, and then space is pressed, Thumb-Key replaces the last character before the cursor with a comma instead of a space. This could potentially lead to loss of important information, like altering a password unintentionally.

Steps to Reproduce the Issue

1. Open an application where you can type text using Thumb-Key.
2. Type any word or sentence and insert a single space.
3. Using your finger, manually move the cursor to a position right after a word (do this directly on the screen, not using Thumb-Key).
4. Press the spacebar. Observe that the last letter of the word you placed the cursor after is replaced with a comma.

Chat GPT says that it can check to make sure it's a space that it's replacing before replacing it with a comma. Here's a link to that conversation for your convenience. https://chat.openai.com/share/e052adea-ecaf-4187-a696-625e15d30eff
