When typing in a field that already has text and punctuation, an extra copy of the punctuation mark is added each time the target text is subsequently edited. For example:

Hello, becomes Hello,, then Hello,,, etc.

Steps to Reproduce:

1. Launch AIM and start adapting
2. Click on a field with punctuation and accept the edit.
3. Click on the same field and type Enter to accept the edit again.

--> note that an extra copy of the punctuation is copied to the target text.
