Summary0002710: Freecad doesn't show sketch elements added when overconstrained
DescriptionIf you have an overconstrained sketch, Freecad will not show sketched features drawn without any constraints. The features show up by either adding another feature and creating auto constraints or by saving and re-opening the file. If you are in the state with any "hidden" features and press undo (cmd+z), Freecad crashes.
This bug works the same way in both version 0.16 (6706) and 0.17 (8471).
Steps To Reproduce1. Open the attached file (HiddenSketchFeatures017 or 016) file
2. Add any number sketch elements without auto-added constraints. They will all be hidden. Some will even crash Freecad immediately (like the more advanced such as rectangle or slot).
3. Add any constraint. The hidden elements will now appear.
4. Use the "Undo" action (cmd+z or the Undo menu item). Freecad will crash when removing one of these hidden (or previously hidden) elements.

Linked 0002650 even though not sure they are related beside the undo issue. The OP of 0002650 is unresponsive and didn't post a sample file. So I'm linking for recognition JIC it has something to do with this ticket.
