react.componentStack event context#21183Conversation
The `react.componentStack` event context set by `captureReactException`
on every captured error never gets sourcemaps applied, so the string it
ships is mostly unreadable. For React >= 17 the same component stack is
already attached via `error.cause` (which does get sourcemaps); for
React < 17 it offers little value either.
Drop the `setContext('react', ...)` call. The surrounding `withScope`
wrapper has no other mutation, so collapse it to a direct
`captureException` call and drop the now-unused `withScope` import.
Sync the spy assertions in `errorboundary.test.tsx`: remove the
`scopeSetContextSpy` setup and rewrite the `cause.stack`-versus-mock
expectations to `expect.any(String)` — the strongest invariant we can
still observe once the spy is gone, since the underlying `setCause` /
`errorBoundaryError.stack = componentStack` chain is unchanged. The
negation case in the recursive-cause test collapses into the existing
`cause.name` assertion, with an inline comment explaining why the
original (non-ErrorBoundary) cause is preserved when the chain loops.

Leftover mockClear() call on non-spy method breaks tests
High Severity
The vi.spyOn(mockScope, 'setContext') call was removed, but the afterEach block still calls (mockScope.setContext as any).mockClear(). Since mockScope.setContext is no longer a spy, it's a plain Scope method without a .mockClear() property — this will throw a TypeError at runtime, causing every test inside describe('ErrorBoundary', ...) to fail.

Summary
Removes the
react.componentStackevent context set bycaptureReactException.The shipped string never has sourcemaps applied, so it's mostly unreadable in the Sentry UI. For React >= 17 the same component stack is already attached via
error.cause(which does get sourcemaps); for React < 17 it offers little value either. Maintainer-confirmed in #20094.Root cause
captureReactExceptionwrapped the capture inwithScopesolely to attach thereact.componentStackcontext. With that context gone thewithScopewrapper has no other mutation, so it collapses to a directcaptureExceptioncall (andwithScopedrops out of the imports).Test sync:
scopeSetContextSpyinerrorboundary.test.tsxis removed. The twoexpect(cause.stack).toEqual(scopeSetContextSpy.mock.calls[...])assertions becomeexpect.any(String)— the strongest invariant left now that the spy is gone, since the underlyingsetCause/errorBoundaryError.stack = componentStackchain is unchanged. The recursive-cause negation collapses into the existingcause.nameassertion, with an inline comment explaining why the original cause is preserved when the chain loops.Fixes #20094
