The line-lock from the previous fix made anchors immovable across lines — dragging a handle vertically no longer extended the selection, losing the native multi-line behaviour. New contract: a handle anchor moves RELATIVE to its own visual line. The finger's vertical displacement from the grab position, in whole visual line heights, selects the target line (under half a line: the anchor's own line); the finger's x is projected onto that line. A stationary or horizontal drag never moves the anchor off its line (the grab-box press stays safe — the original bug is gone), while a deliberate vertical drag walks the anchor across lines. The mapping is relative, not the finger's absolute line, because the 48dp grab box is centred below the line: a low press tracking the finger's absolute line would first drag the anchor the wrong way, through a collapse, before reaching the anchor's line. Verified on device: end handle dragged down extends the selection across the newline; start handle dragged up extends it onto the previous line; horizontal drags still shrink along the line without clearing. Tests mutation-verified against both the pre-fix mapping and the absolute-finger-line variant. Docs section 17 updated. |
