Sketching photos undo issues

[erpas]

When sketching a photo, the list of tapped points doesn't get reset when you undo the shape. To recreate:

• tap the photo a few times to create straight lines
• undo the shape
• optional: change the colour to see the duplicated shape
• tap the photo again -> the undone shape is back with the newly created point added

The issue stems from the tapping. The support for tapping is somehow limited and should actually not create straight lines! It is one of the known issues that we will try to fix in next releases.
