Per DOM §2.9 step 4 substep 8 ("Inner invoke"), an exception thrown by a
listener callback must be reported to the realm's global, not propagated
out of `dispatchEvent`. Subsequent listeners on the same target and the
rest of the capture/bubble walk must still run.
Both `EventManager.dispatchPhase` (DOM targets) and
`EventManagerBase.dispatchDirect` (Window/XHR/AbortSignal/etc.) wrapped
the V8 callback invocation in raw `try`, so a listener throw aborted the
whole dispatch and surfaced as an uncaught exception at the
`Runtime.evaluate` boundary. The inline-handler invocation a few lines
above already used `catch |err| log.warn(...)`; this just extends the
same shape to the listener switch.
Closes#2367
This fixes 2 separate issues, driven by the [very] broken
/dom/ranges/Range-insertNode.html WPT test.
The first, and simplest, is that when a script element is cloned, its executing
_executed and _force_async flags need to be copied. This prevents double-
execution.
The second is more complicated: dom version tracking (as a caching mechanism
used in various live collection) has to be against the node's owning frame, not
the frame that's executing the JavaScript. This includes both the version
checking and version change (on dom mutation). This introduces a relatively
expensive node -> document -> frame on every mutation and cache read. This is
potentially worth optimizing somehow, in a follow up PR. Two options come to
mind:
1 - Track a single dom version on the Page. Mutation in frame1 invalidates
frame2.
2 - Optimize for the frame-less case. If a page has no frame, then the calling
context should be equal to the owning document's frame.
When Fetch.httpErrorCallback rejects the promise, microtasks are run. Those
microtasks could do anything, including triggering a frame shutdown (e.g. via
a navigation event). The result is that we end up with
httpErrorCallback
httpShutdownCallback
And the code simply isn't designed to handle that. httpErrorCallback now takes
control of the cleanup, capturing the `self._owns_response` in a local, and
disabling so that any nested `httpShutdownCallback` are noops.
Integrates the Tavily Search API as the primary search provider when
TAVILY_API_KEY is set. Falls back to scraping Google and DuckDuckGo
on failure or if the key is missing. Updates zenai dependency.
Wire the existing multipart encoder (FormData.multipartEncode) into the
fetch and XHR body paths. Previously both entry points typed their body
parameter as ?[]const u8, so the JS->Zig bridge silently coerced any
FormData JSValue via toString() and emitted "[object FormData]" with
Content-Type: application/x-www-form-urlencoded.
Introduces a BodyInit tagged union covering FormData, URLSearchParams,
Blob, and bytes. A small extract() helper returns the serialized bytes
plus the spec-mandated default Content-Type (Fetch §6.5 step 8 / XHR
§4.7.6 step 4). Both Request.init and XMLHttpRequest.send apply the
default Content-Type only when the caller hasn't already set one.

Add worker.setInterval, clearInterval, setTimeout, clearTimeout by extracting
the scheduling logic from Window and making it use Execution rather than Frame.
- Fix typo in REPL info message.
- Optimize Recorder to avoid unnecessary allocations.
- Simplify field type detection in SlashCommand using stringToEnum.
- Remove unused yellow ANSI constant in Terminal.
- Shorten log message in McpServer.
Restricts self-heal turns to only allow page-local commands. Commands
like `goto` and `eval_js` are now ignored to prevent the model from
navigating away or executing arbitrary scripts during healing.
