Unable to Load multiple Power BI Report in Power BI Embedded

I am trying to Load multiple report on different iframe at a same time , for that I am getting different token , fetching report id , prearing the required object to load the object and then one by one giving a call for Powerbi.embedded with required configuration and placeholder where it get loaded. All the call going at a same time as well but whosoever response come first that report only gets loaded other will just show Loading screen only.

e.g I have report 1,2 and 3 , giving a call of all 3 report with required parameter now let say report 2 response come faster then in webpage iframe i can see report 2 full loaded with visuals inside those report while report 1 & 3 will just show iframe with loading symbole only , report not loaded for this and visual also not visible.

NOTE : I am not getting any error in developer tool , assumpution once one report load other operation getting aborted why ? can't I load multiple report ?
