fix(runtime): update test to reflect legacy-HTML passthrough branch

hqhq1025 · hqhq1025 · commit 364059c74454 · 2026-04-20T23:22:36.000+08:00
Runtime's buildSrcdoc gained a short-circuit that returns legacy full
HTML documents (pre-JSX-only snapshots) verbatim so Babel doesn't choke
on the DOCTYPE / &lt;html&gt; tokens. The accompanying test still asserted
the old "wrap everything" behaviour and broke CI after the rule-demotion
commit let the runtime package's tests actually run.

Also: fold in a trailing biome-format fix on CanvasErrorBar.tsx.
