Description

XSLT3 test case mode-1437a is failing XTTE3090 (no context node when evaluating template).

The reason is that the code implementing deep-skip (which for a document node actually invokes templates on the children) is setting the current iterator to a Join iterator without wrapping it in a Tracker. This means that the value of "current" is undefined, triggering the error condition.

Fixed. Changed the deep-skip code (mode.js#128) to

                    case K.DOCUMENT_NODE:
                    case K.DOCUMENT_FRAGMENT_NODE:
                        const c2 = context.newContext(false);
                        c2.focus = Iter.Tracker(Axis.child(item));
                        mode.applyTemplates(c2, out);
                        break;
