Mobile view is not being shown for embedded powerbi report

We have created a PowerBI report having both the desktop verion and mobile virson.

Its showing desktop and pone view properly when we are testing at following sample site after putting correct information. 

https://microsoft.github.io/PowerBI-JavaScript/demo/v2-demo/index.html

But when we open the website on mobile It is still showing the desktop version of the report.

File version used of powerbi.js file is 'powerbi-client v2.5.1'.

The HTML and javascript used is provided below

We are also appending '&isMobile=true' with embed report url.

Are we missing any reference to show the mobile version.
