Description

That should be fixed prior to 2.0, pretty scary behavior. When a layer symbology is set to categorized, graduated, or rule-based, all features will disappear when editing feature(s) on that layer. If the user then leave the edit mode (saving changes or not), all features will reappear.

Steps to reproduce:
1. Load the attached shapefile (featuresgone.shp) into a new project
2. Open the featuresgone layer property window, switch style to categorized (using 'blah' column), and apply
3. Toggle edit mode on for the featuresgone layer
4. Move a feature with the node tool

At that stage, only the feature moved will remain visible, all the other features are gone. The features are still there, simply not drawn. Saving the layer by leaving the edit mode will re-draw all features.

Data stays, but it's super scary behavior :)
