Anychart doenst work in Tab

Hello Expert, I am trying to use anychart (type heatmap) with JSON data/layout. I want to display heatmap data under tab container .  But what i observed, it doesn’t load that heatmap data on first click under tab widget. I have to do back and forth several times to see it.  This happens only with Heatmap chart becasue i dont see any issue with other charts which gets rendered as expected. Is there any bug  or am I missing somethingf? Additional :  I don’t see any problem in Microflow which returns data correctly and no error on console.
