When uploading a file the option "allowedExtensions" cares about the case sensitivity and blocks f.e. a file called "image.PNG" when allowedExtension is set to "png" (lower cased). Expected: Case sensitivity will be ignored or could be activated/deactivated by another option.
I came across an issue in Kendo Upload UI for Vue. The tooltip is not getting changed on file drag. I could reproduce the same in the official kendo website.
