A Page now has a StyleManager. The StyleManager currently answers two questions:
1 - Is an element hidden
2 - Does an element have pointer-events == none
This is used in calls such as element.checkVisibility which, on some pages, can
be called tens of thousands of times (often through other methods, like
element.getBoundingClientRect). This _can_ be a bottleneck.
The StyleManager keeps a list of rules. The rules include the selector,
specificity, and properties that we care about. Rules in a stylesheet that
contain no properties of interest are ignored. This is the first and likely
most significant optimization. Presumably, most CSS rules don't have a
display/visibility/opacity or pointer-events property.
The list is rules is cached until stylesheets are modified or delete. When this
happens, the StyleManager is flagged as "dirty" and rebuilt on-demand in the
next query. This is our second major optimization.
For now, to check if an element is visible, we still need to scan all rules.
But having a pre-build subset of all the rules is a first step.
The next step might be to optimize the matching, or possibly optimizing common
cases (e.g. id and/or simple class selector)
Adds support for `pointer-events: none` in interactivity classification
and expands `checkVisibility` to include `visibility` and `opacity`.
Refactors CSS property lookup into a shared helper.
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.
- 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.
- 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.
* Refactored tag ignoring logic to use the el.getTag() enum switch
instead of string comparisons, improving performance and safety.
* Replaced string comparisons for interactive roles with
std.StaticStringMap.
* Renamed internal dumpNode method to dump for brevity.
