Issue Summary

Re-rendering an <ViewPage> component from @atlaskit/embedded-confluence at a high frequency can cause memory usage in the embedded iframe to grow over time.

Steps to Reproduce

Step 1: Embed a Confluence page via @atlaskit/embedded-confluence.
Step 2: Cause the component to re-render continuously.
Step 3: Leave the page open and observe memory usage growing over time.

Expected Results

Memory usage remains stable.

Actual Results

Memory usage grows continuously while the component re-renders.

Workaround

Avoid unnecessary re-renders of the embedded component. Check that props passed to <ViewPage> (especially object/array props such as style, navigationPolicy, allowedFeatures) are stable across renders.
