If I give myself a sign with BlockEntityTag, and there's space in text, the text after the space doesn't get render

/give @p sign 2 0 {BlockEntityTag:{Text2:"{\"text\":\"Item Manipulator\",\"color\":\"blue\",\"bold\":true}",Text3:"{\"text\":\"by Insane96MCP\",\"color\":\"gold\",\"bold\":true}"},display:{Name:"Custom Sign"}}

I've tried relogging into the world, but nothing changed.

Maybe is related to: MC-105982
