(Issue #MS-IS-1710-984) This is a tricky bug, as it is dependent on the Machines speed

This is a tricky bug, as it is dependent on the Machines speed to see visually, and at the time of recording, my recorder was not at the correct frame rate to capture this, but still, you will see that the System has logs on Network and the Renderer also captures the same.

Prerequisites:

1. A Feature Page set up to load the most basic html with no JS code in an IFrame

2. a no js code html url

Steps to Reproduce:

1. Go to https://sandbox.hivedmusic.com/channels and enable Application recording, and network recording
2. Click on the Hamburger Icon -> Click on "NO JS Test"
3. Expected: The IFrame is rendered once
4. Actual: The IFrame is rendered twice based on various uncontrollable factors, but mostly yes.
5. Networks tab will show that the html file was fetched twice, and the performance recording will show the two repaints.

Severity: HIGH

This issue causes a flash on the screen when loading our Mapbox integration, causing the mapbox to be reloaded.
