The increase/decrease icons in the select box don't appear centered after upgrading to latest 2017.1.118.
I attached some screenshots that show the new behaviour, I used telerik.com's demos and switched the version on the edit example.
Tested with all 3 major browsers.
Thank you for bringing this to our attention. We are aware of the issue and it has already been addressed (Github issue here: https://github.com/telerik/kendo-ui-core/issues/2643). Expect this to be fixed in the upcoming service pack.
