When calculating accessible names for elements without explicit labels, multiple descendant text nodes were previously concatenated directly together. This adds a space between distinct text node contents to prevent words from sticking together.
Previously, semantic_tree_text hardcoded prune = false, which bypassed the structural node filters and allowed empty none nodes to pollute the root of the text dump.
This prevents token bloat in JSON/text dumps and ensures that StaticText leaf nodes are not incorrectly pruned when structural containers (like none, table) hoist their text.
This fixes a bug where only the first text node was being returned, causing fragmented text nodes (e.g. <span>Sub</span><span>mit</span>) to be missing their trailing text.
- TreeWalker.Full instead of FullExcludeSelf so querying a specific
nodeId evaluates the root element itself
- resolve href to absolute URL via URL.resolve
- isDisabled checks ancestor <fieldset disabled> with legend exemption
- parameter order: allocator before *Page per convention
Allows checking if a direct listener exists, if it doesn't, event creation can
be skipped.
I looked at a couple sites, the benefits of this is small.
Most sites don't seem to trigger that many direct dispatches and when they do,
they seem to have a listener 50-75% of the time.
- Use `checkVisibility` for more accurate element visibility detection.
- Add support for color, date, file, and month AX roles.
- Optimize XPath generation by tracking sibling indices during the walk.
- Refine interactivity detection for form elements.
Returns a structured list of all interactive elements on a page:
buttons, links, inputs, ARIA widgets, contenteditable regions, and
elements with event listeners. Includes accessible names, roles,
listener types, and key attributes.
Event listener introspection (both addEventListener and inline
handlers) is unique to LP — no other browser exposes this to
automation code.
- Use a reusable buffer for XPaths to reduce allocations.
- Improve `display: none` detection with proper CSS parsing.
- Pass parent name to children to avoid redundant AXNode lookups.
- Use `getElementById` for faster datalist lookups.
- Add more structural roles (banner, navigation, main, list, etc.).
- Implement fallback for accessible names (SVG titles, image alt text).
- Skip children for leaf-like semantic nodes to reduce redundancy.
- Disable pruning in the default semantic tree view.
Instead of always returning zeros, delegate getBoundingClientRect and
getClientRects to the common ancestor container element. Return zeros
only when the range is collapsed or has no element ancestor.
