The fix in move_with resets select_mode to Character after movement, but move_offsets_with (used by move_to_enclosing_bracket, select_delimiters_impl, etc.) does not. This leaves the original bug unfixed for those code paths: after moving the cursor via these methods, Shift-click may still extend from a stale word/line boundary.
move_with resets select_mode to Character regardless of whether the movement actually changed the selection. If the cursor is at a boundary and movement is a no-op (e.g., pressing right at end of line), the mode is still reset. This can break empty line selections that are 'moved' without changing the cursor position, causing subsequent Shift-click to extend character-wise instead of line-wise. The PR description states 'whenever it changes the selection', but the code does not check for change.
if self.selections_changed { self.collection.select_mode = SelectMode::Character; }
