Fix manual resize requests to always dispatch messages

[Copilot]

The setTargetOrigin integration test was failing because manual resize requests were being ignored when dimensions hadn't changed. Additionally, the resize(rightMostElement) test was failing because parent-initiated resize requests were being throttled.

Changes

• packages/child/size/content.js: Added MANUAL_RESIZE_REQUEST and PARENT_RESIZE_REQUEST to the switch cases that force message dispatch, ensuring resize() and parent-initiated resizes always send messages regardless of size delta

• packages/child/send/size.js: Modified the sendPending throttle check to exclude manual and parent resize requests, allowing them to bypass the pending check similar to OVERFLOW_OBSERVER

Context

// Previously, this would not send a message if already 10x10
parentIFrame.setTargetOrigin('http://example.com')
parentIFrame.resize(10, 10)  // Silent no-op if size unchanged

// Now correctly dispatches with new target origin

The issues were:

1. getContentSize() returned null for unchanged sizes, preventing dispatch() from being called
2. The sendPending throttle blocked parent-initiated resize requests when another resize was already queued

Manual and parent resize requests must always be processed immediately, even when dimensions are identical or another resize is pending.

The problem is we are running the tests too fast, we need to wait for the animation frame to clear before running this, to avoid the throttle.

@copilot The test is still failing for a different reason.

...

Fixed in commit c5f7188. The issue was that the sendPending throttle check was blocking PARENT_RESIZE_REQUEST when another resize was already queued. Modified the condition to exclude manual and parent resize requests from the pending check, allowing them to bypass throttling just like OVERFLOW_OBSERVER.

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

@copilot would it make more sense to to add OVERFLOW_OBSERVER to IGNORE_DISABLE_RESIZE or is it used elsewhere?

No, OVERFLOW_OBSERVER serves a different purpose. It should bypass the sendPending throttle (to detect overflow changes quickly) but should NOT bypass autoResize=false (respects user settings). In contrast, MANUAL_RESIZE_REQUEST and PARENT_RESIZE_REQUEST need to bypass both checks since they're explicit user/parent actions. The current implementation correctly handles these distinctions.
