Kendo tabstrip wraps a < li > tag that has ID attribute. In the official kendo website, the ID is a unique string - 'k-tabstrip-tab-' followed by a random alphanumeric string. for example. 'k-tabstrip-tab-jasdj656aSfJASDJH3'. But in my version of kendo it is not generating this random alphanumeric string but instead it is 'k-tabstrip-tab-' followed by a decimal number as shown in the image.
It might not seem like a big deal but we are using multiple tabstrip in the same page so it is generating duplicate IDs. Does anyone know why this is happening ??

Apparently, this is a known issue in the older version of kendo and has been addressed since kendo version 13.1.0
