Conversation
The hosted cart iframe did not declare a Permissions Policy, so the Payment Request API was blocked inside it. Add `allow="payment"` to both the mini cart iframe and the inline one. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

Problem
The hosted cart
<iframe>did not declare a Permissions Policy. Without one, the browser blocks the Payment Request API inside the frame, so payment flows that rely on it cannot start from the embedded cart.Change
Add
allow="payment"to both iframes rendered byHostedCart:Two lines, no behaviour change beyond lifting the policy restriction.
Notes for the reviewer
v5.0.6-beta.0version bump commit, already tagged and published to thenextdist-tag.v4.29.8-beta.1. The diff there is byte-identical.Verification
allowis a valid property ofIframeHTMLAttributesin the installed React types. Worth flagging honestly: the local install has React 19 types while the v4 backport declares@types/react ^18.3.1, so the backport was checked against the v5 types rather than its own. In the worst case that would surface as a type error, never at runtime.🤖 Generated with Claude Code
