EditablePage: Set loadOverlay margins explicitly, set loader invisible during loading
When items are being loaded, they should be invisible so they do not flicker or otherwise show up during creation.
Set the loadOverlay margins to fit their parent. Previously if parent had margins, loadOverlay would also use those same margins, not hiding the page fully. This makes sure we ignore those margins for loadOverlay.
