After upgrading from 4.1 version of DHTMLX Gantt to 5.2 I encountered a problem with rendering the chart in a 'hidden' non-active bootstrap tab. Even though div has HTML attribute width and height defined, the javascript height property returns 0 height.
I tried to render gantt chart again on onclick event of a tab switch button, but it seems that transition effect does not display the div soon enough, so it only renders the gantt chart on the second button click, when the div is already displayed.
Did anyone solved this issue without writing an shown.bs.tab event listener?
