Cursor jumps between lines when navigating through formatted outline text

Steps to reproduce:

1. Paste the following outline:

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Morbi ac tellus nec ipsum gravida vulputate id id nibh. Aliquam cursus in elit eu imperdiet.
Quisque porta magna id porta elementum. In sodales, erat eu bibendum eleifend, nisi ipsum mattis tortor, vel pharetra nulla orci consectetur lacus.
Donec iaculis malesuada interdum. at ac metus non, molestie vestibulum sapien. Quisque ultricies dictum arcu ut rhoncus. Aenean vel gravida est. Suspendisse enim neque, imperdiet eget blandit rhoncus, ultricies eu enim. Suspendisse potenti. Maecenas laoreet justo diam, et facilisis sem porttitor id. Curabitur at mollis justo. Mauris non ultrices ante. Aenean tempor pretium blandit.
Morbi elementum augue laoreet dolor rutrum, a bibendum lectus condimentum. Pellentesque ac felis at nisl pharetra tempus. Nam interdum leo id elit finibus, vitae tincidunt eros efficitur. Nulla facilisi. Suspendisse venenatis ligula et lacus viverra, eu accumsan mi molestie. Fusce sit amet condimentum nulla. Ut nec nisi magna. Praesent sit amet lacus volutpat, vehicula enim eget, dignissim nunc. Donec id tincidunt ipsum.
Pellentesque lacinia varius nisl at eleifend. Sed laoreet neque et pretium vehicula. Vestibulum in consequat massa, vel viverra nisl. Phasellus imperdiet, lectus a porta imperdiet, risus massa ultricies orci, sed tempor neque dui in tortor. Vestibulum nec lacinia enim, non finibus enim. Quisque nec elit elementum, sodales eros ac, aliquet lectus. In tincidunt malesuada urna vel tincidunt.

1. Place the cursor at the beginning of the first line.
2. Move the cursor down line by line using the keyboard shortcut / arrow key.

Actual result:
Because of the formatting, the cursor does not stay at the beginning of each line. Instead, it starts jumping between different positions within the lines.

Expected result:
When moving down from the beginning of the first line, the cursor should remain aligned with the beginning of each subsequent line, regardless of bold formatting inside the text.

@yasieck Thanks for the report, and for the detailed steps.
Moving down should keep the caret at the start of each line. What you saw is not intended. I will fix this.

Fixed in 1.15.
