Patch Changes
- edb1fa7: Keep code-like blocks left-to-right inside RTL plans. Code, code-tabs, diff,
file-tree, annotated-code, API endpoint, OpenAPI spec, JSON explorer,
data-model, schema-editor, diagram, mermaid, and wireframe blocks now pin their
outermost element todir="ltr"(via a sharedltrCodeBlockPropshelper) so
they no longer inherit a Persian/Arabic plan document's RTL direction and render
reversed. Prose, rich-text, and callout blocks intentionally stay RTL.
