Summary

• Append client-mounted icon CSS when cssLayer is configured, preserving the app's existing cascade-layer order.
• Keep the current first-stylesheet placement for unlayered icon CSS.
• Add regression coverage for both placement rules.

The reported stylesheet insertion causes a full-document style recalculation for late icons, with a measurable impact on mobile interaction latency.

Fixes #543

Walkthrough

mountCSS now uses insertIconStyle to add generated icon styles. When a CSS layer is configured, the function appends the style to document.head. Otherwise, it inserts the style before the first style element or stylesheet link, or appends it when neither exists. Tests cover both ordering paths.

Priority: Normal

Estimated code review effort: 2 (Simple) | ~10 minutes

Severity of issue fixed: Medium

Merge Risk: Minimal · up to df7d1

The change preserves existing unlayered behavior while appending layered icon styles as intended, with no identified merge-blocking risk.

Full details: Title check

Explanation

The title names the main change: appending client-mounted icon CSS when cssLayer is set, so late icons keep the cascade layer order. The changeset adds insertIconStyle to style-order.ts, switches css.ts to use it, and adds tests for layered and unlayered placement. The title uses the conventional fix(css) prefix and is specific, 53 characters.

Full details: Description check

Explanation

The description states the intent: append icon CSS when cssLayer is configured, keep first-stylesheet placement for unlayered CSS, and add regression tests. It also lists the commands run to verify the change. It matches the changed files in css.ts, style-order.ts, and style-order.test.ts.

Full details: Linked Issues check

Explanation

Issue #543 requires appending client-mounted icon CSS when cssLayer is configured and retaining first-stylesheet placement otherwise. css.ts now calls insertIconStyle with options.cssLayer. The helper appends layered styles and preserves the previous insertion logic for unlayered styles. test/style-order.test.ts covers both placement rules.
