This is one more hurdle on the road to launching Extended Text Metrics. Hopefully I've learned some things since adding `lang`.

File third_party/blink/web_tests/external/wpt/html/canvas/tools/yaml/text.yaml
Line 1506, Patchset 7 (Latest): if ('{{ ctx_writing_mode }}' == 'vertical' && '{{ text_direction }}' == 'rtl')
