Dragging from right to left in a canvas text field only moved the cursor. The hidden input behind the field got every selection sorted and without a direction. Its selectionchange echo then handed back the sorted range, and the anchor jumped to the mouse on the first move. - KeyboardBridge sets the selection with 'backward' when the focus lies before the anchor, and reads selectionDirection when the input reports a change. - TextField passes anchor and focus through unchanged. Its own sorting is gone. - Shift+Left runs through the same path. The cursor should now sit at the moving end there too. This is not tested on its own. Tests: - ./check.sh: 167 files, 2435 tests, CHECK EXIT 0 - e2e 2: ALL PASSED, 25 checks. New check 2d-ii drags right to left in the name field and reads start 0, end 13, direction backward. - Counter-check without the direction: 2d-ii fails with end 2, the reported symptom. - e2e check total in README goes to 1401 (computed, not run in full).
