This happens only when dashType configuration is not \"solid\", and in Firefox and IE11 only.\r\n\r\n### Reproduction of the problem\r\nThe issue occurs when we select a small portion of the graph using mouse by holding the shift key i.e. select-zoom functionality of graph.\r\nWhen we repeatedly select a small portion of graph, after few selections, the graph starts to hang and eventually distorts.\r\n\r\nDojo:\r\n[http://dojo.telerik.com/OQuZU/2](http://dojo.telerik.com/OQuZU/2)\r\n\r\n### Current behavior\r\n\r\nThe described behavior is observed in the following video:\r\n[http://www.screencast.com/t/rrPf1xNF](http://www.screencast.com/t/rrPf1xNF)\r\n\r\nSometimes the graph inverts after repeated selections.\r\nPlease check the video below for this:\r\n[http://www.screencast.com/t/Lyp26ptOM4](http://www.screencast.com/t/Lyp26ptOM4)\r\n\r\n### Expected/desired behavior\r\nZooming functionality to work as expected (like in Google Chrome)\r\n\r\n### Environment\r\n* **Operating System - Windows 8.1\r\n* **Browser - Firefox\r\n* **Browser Version - 47.0.1\r\n* **Kendo UI Version - 2016.2 714\r\n* **Mouse – all"}}
