fix(clerk-js): Invalidate server cache for after-auth custom flows

[LauraBeatris]

Description

Previously, the server-side cache of clerk.session would not be properly invalidated on setActive with pending session, causing if (clerk.session.currentTask) to fail.

This fix checks if setActive is not performed within internal components context, and only then invalidates the cache.

CleanShot.2025-07-29.at.11.00.14.mp4

if (signInAttempt.status === 'complete') {
    await setActive({ session: signInAttempt.createdSessionId })
 } 

 if (clerk.session?.currentTask) {
    router.push('/sign-in/tasks/select-organization')
    return;
  }

📝 Walkthrough

Walkthrough

A patch was applied to the '@clerk/clerk-js' package to address an issue with server-side session cache invalidation following custom authentication flows. The internal method #handlePendingSession in the Clerk class was updated to conditionally invoke two hooks, onBeforeSetActive and onAfterSetActive, before and after the session handling logic. These hooks are triggered only when not navigating within components, as determined by a private flag. The hooks are sourced from global window properties in browser environments and default to no-ops otherwise. Additionally, the bundlewatch configuration was updated to increase the maximum allowed bundle size for ./dist/clerk.browser.js from 72.2KB to 74KB. No public or exported entities were changed.
