To reproduce:
- Translate "Venäjän–Turkin sota (1735–1739)" from Finnish (fi) to Ladino (lad).
- Click in the paragraph that begins with the words "Puolan perimyssodan päättymisen".
- Move the caret to the beginning last line of the paragraph in the source text that was inserted to the translation column.
- Press the right arrow key to move the caret until it gets to the end of the line.
Expected: When the caret gets to the end of the line, pressing the right arrow key again doesn't move the caret.
Observed: When the caret gets to the end of the line, pressing the right arrow key again moves the caret to the beginning of the line, and it continues as an infinite loop.
