fix(a11y): allow resource load and error handlers by Mnigos · Pull Request #11650 · biomejs/biome

Mnigos · 2026-09-06T23:19:29Z

Summary

Fixes #11647. Allow resource load/error handlers on non-interactive elements in the HTML and JSX analyzers; retain diagnostics for mouse, keyboard, and focus handlers.

AI assistance: Codex investigated the issue, wrote the code, tests, changeset, and this description, and ran validation. A separate Codex agent performed static review.

Test Plan

New HTML/Svelte valid-resource fixtures fail on unpatched main.
Svelte, HTML, and TSX fixtures cover load/error handlers and combinations with click, keydown, and focus handlers.
cargo test -p biome_html_analyze -p biome_js_analyze --no-fail-fast: 3,901 passed, 4 ignored.
just gen-rules, just gen-configuration, just f, and just l.
Diff whitespace check passes excluding generated diagnostic snapshots, which retain the test harness output.

Docs

Updated both rule descriptions and added a patch changeset.

Walkthrough

The noNoninteractiveElementInteractions rule now allows image load and error handlers in HTML, Svelte, and JSX. The analyzers no longer classify image events as user-interaction handlers. New fixtures verify that resource handlers do not produce diagnostics, while combinations with click, keyboard, or focus handlers still do. A patch changeset documents the fix.

Merge Risk: ⚪ Minimal · up to c6b0b

The rule now permits non-interactive resource load and error handlers while retaining accessibility diagnostics for mouse, keyboard, and focus interactions. No current merge-blocking risk is identified.

Looking at the source rule, I can't figure out why these cases were flagged. Resource load/error event listeners obviously does not make an element interactive...

Tentatively approving, in case there's some additional context im missing
