EvView: Fix cursor movement when logical and visual line order differs
Make sure not to move the caret in the wrong direction when restoring
the visual line X offset, in case the visual and logical order is
slightly different.
The algorithm used to move the cursor on the next line and restore the
X position across lines works as follows:
1. Move `cursor_offset` to the next line by incrementing it until
reaching a line break;
2. Find the Y coordinate corresponding to the new cursor_offset;
3. Find the text closest to the new Y coordinate and the previous X
coordinate.
4. Move cursor_offset to the text at this new (X, Y) location.
The issue lies in step 3, which can find a position on a different line
than expected in case several lines have a nearly the same Y position.
