Previously, it was possible for an up/down arrow press to place the cursor in the middle of a multi-code point grapheme cluster. We want to prevent this in a way that matches the behavior of other browsers. Both Chrome and Firefox will map the starting position to a visually equivalent position in the target line with harfbuzz and ICU segmenters. The need for this is explained in a code comment. The result is a much more natural feeling of text navigation.
