Changing Eeschema label type doesn't set the connected flag

[Seth Hillbrand]

Place a global label on a wire. Note that it is correctly connected (No square). Change the type to hierarchical label. Note that the label now thinks it is disconnected (square shows). Press 'M' on the label, don't move it and click to place. Note that the label is again connected.

Desired behavior:
Changing the label type should not change the connected flag of the label.
