chore(deps): bump mixpanel-browser from 2.59.0 to 2.70.0 in /apps/block_scout_web/assets

[dependabot]

Bumps mixpanel-browser from 2.59.0 to 2.70.0.

Release notes

Sourced from mixpanel-browser's releases.

rrweb upgrade and stricter disable_persistence

• Upgraded rrweb to use a Mixpanel-maintained fork containing performance fixes from the rrweb team (https://github.com/mixpanel/rrweb)
• Added additional handling for disable_persistence so that sessionStorage and IndexedDB are not modified
• Fixed TypeScript imports for custom builds

Rage-Click detection and other updates

This release adds support for Rage-Click tracking as part of the Autocapture subsystem. It is enabled in the default autocapture config, and can also be controlled explicitly with the rage_click autocapture init option.

Other updates include:

• Session Recording now blocks <audio> tags by default
• A new Feature-Flag method flags.update_context() facilitates updating context variables and refetching variants

Fixes and minor updates

• get_api_host() is now used consistently across the SDK to ensure that per-endpoint API host configs are respected everywhere
• A fix is included for the ordering of (asynchronous) operations when calling mixpanel.reset() while a session recording is active
• Default Feature Flag context now includes device_id alongside distinct_id
• $experiment_started events now include several API-latency-tracking properties

Fine-grained API host configuration and session recording fixes

A new api_hosts configuration option enables different endpoints (events, profiles, groups, session recordings) to be sent to different hosts, for selective proxying, e.g.:

mixpanel.init('<TOKEN>', {
  api_hosts: {
    // proxy only session-recording requests, and leave the rest on the default host api-js.mixpanel.com
    'record': 'https://my-proxy.com',
  },
});

This release also fixes a race condition when calling mixpanel.reset() while a session recording is active, and adds an initial TypeScript types.d.ts file.

Updates to revenue, session recording, autocapture, etc

This release packages up changes and improvements to several subsystems:

• The long-deprecated mixpanel.people.track_charge() method now only prints a console error and no longer sets a profile property or produces any other change. The old version of Mixpanel's Revenue analysis UI has been replaced by a newer suite of analysis tools which don't depend on profile properties (see https://docs.mixpanel.com/docs/features/revenue_analytics).
• Autocapture click tracking properties now include page height and width.
• Session recording now stops when mixpanel.reset() is called.
• New init optionapi_extra_query_params adds support for appending arbitrary query string params to tracking requests (useful for non-standard proxy setups)
• The API of the Feature Flagging system (under development) has been revised
• Whale Browser is now detected automatically

Dependency and build upgrades

This release upgrades session-recording library rrweb to the latest alpha version. In conjunction, the SDK's build process has been refactored and Closure Compiler updated.

Native UUID and JSON serialization

• UUIDs are now generated as UUIDv4. When available, the native randomUUID() from the Crypto API is used; otherwise the library falls back to a simple custom UUIDv4 implementation.
• When available, the library now consistently uses native JSON.stringify() for serializing request data, only falling back to the older custom JSON encoding implementation if the environment doesn't have native JSON APIs.
• Fixes a Session Recording race condition where sometimes the idle timeout is reset past when it should have fired due to a backgrounded tab.

Revert event/user queue throttling
