Canvas setting to "display:none" on resize of the Collapsed Tab

[khavrenko]

Env: version 3.12.1, browser Chrome 47.0.2526.106 m (64-bit), OS Windows 7 x64

1. Collapse the Map Section
2. Resize the Browser Screen
3. Expand the Map Section( Now the Map was not rendering (it is blank), instead display:none was attached to the Canvas Element)

Note: when i manually invoke $mapContainer.find('.ol-viewport canvas').show(), map was displayed, but default controls are not working)

P.S. it is the same behavior as tombatossals/angular-openlayers-directive#199

Try to call map.updateSize(); after expanding the map section.
