Lightpanda updates browser engine to support grouped options

Lightpanda has updated its open-source headless browser engine so that option elements nested within optgroup tags are fully accessible to .options, .value, and form submissions. Previously, options inside group tags were invisible to DOM properties and form posts, but this update fixes the non-compliant behavior to ensure standard HTML specification matching.

// ANALYSIS

Precise standard HTML compliance is critical for any headless browser claiming to be a drop-in replacement for headless Chrome.

* Fixes a bug where grouped dropdown options were skipped during JavaScript DOM property reads and form serializations.

* Ensures scrapers, automation scripts, and AI agents don't experience silent data loss when submitting complex web forms.
