Icon set in page properties vanishes when the code get changed

Product: PowerShell Universal
Version: 5.0.11

You brought back the ability to set a page icon in version 5.
I skipped the versions between .7 and .11

Now I noticed that whenever I edit the page code in the web GUI or via Vscode and API, the icon disappears from the properties and is not being displayed anymore.
