BUG: version 0.17.4 the components missing when try to add background image to body

I add domComponents: { storeWrapper: 1 }, when initialize the webeditor, to enable add background image to body.

it works fine when use the local storageManager , but all the components lost when use the remote storageManager

below is the data

{"type":"wrapper","droppable":".container","attributes":{"id":"izmf"},"components":[{"type":"container","classes":[{"name":"container","active":false}],"attributes":{"id":"iboj"},"components":[{"type":"row","classes":[{"name":"row","active":false}],"components":[{"type":"column","classes":[{"name":"col","active":false}],"components":[{"type":"header","content":"Bootstrap heading","attributes":{"id":"iie1"}}]},{"type":"column","classes":[{"name":"col","active":false}]}]}]}]}
