When the remote editor determines if a label extends outside the edge (which is cause for deletion if it's dropped there) it uses the length of the variable name in the label text. For example:
"Text: ${someVariableName}" instead of the result of the variable "Text: 100, 45, 399".
So the label element is actually longer than it looks which causes problems when you're moving it around and it looks like it's fine someplace, but it's actually outside the edge and gets deleted when you drop it.
