4. Place caret between "-" and "e" and hit backspace once. The string will change to "abce-fg" and the caret will be at the end

Expected result: Caret will be placed between "c" and "e"
Actual result: Caret will be at the end

Notes:

• Within the editor, this script works as desired. On an Android build, however, the caret will jump back to the end of the line if a modification was made to the caret position.

• The desired behavior is the one in the Editor, the android build should replicate this!
