Web navigation compatibility research

Through our research we uncovered numerous spec bugs and incompatibilities. In addition we found a rare case where all major implementations agreed on incorrect behavior of the target property of Anchor elements. We filed bugs on each browser and submitted new tests web-platform-tests documenting the behavior. Each of the browsers corrected the behavior, and the web platform is more predictable as a result.
