Playwright fails locator actions on Obscura for two avoidable reasons
that are separate from the missing layout engine. Both have trivial
fixes that unblock the actionability polling loop.
- Element.checkVisibility(opts) was undefined. Playwright >= 1.25 calls
it before every input event and retries until its action timeout if
the method isn't a function. Add a stub that returns true. Without a
layout pass we can't compute it for real, but a permissive stub still
beats the undefined-function path.
- ARIA reflection properties were missing on Element (role, ariaLabel,
ariaSelected, ariaExpanded, ariaHidden, ariaChecked, ariaDisabled,
ariaRoleDescription). Playwright's getByRole and getByLabel locators
read them. Reflect through to the underlying aria-* attributes for
both read and write.
- DOM.getBoxModel and DOM.getContentQuads ignored the objectId param.
Playwright passes only objectId (from a prior DOM.resolveNode), and
the handlers silently defaulted to node 0, so dispatchMouseEvent
always clicked the wrong element. Extract a resolve_node_id helper
that honors nodeId, backendNodeId, and objectId in that order.
- Page.captureScreenshot and Page.captureSnapshot now return a clear
"not supported, use a real Chromium for the screenshot leg" error
instead of the generic "Unknown Page method" fallback. Matches the
pattern already in place for Page.printToPDF.
Partial fix for #45. The architectural blocker (no layout engine, so
multi-element click coordinates are wrong) is unchanged.
