Hey @riteshsaini
One of your best first step troubleshooting options would be to examine the DOM directly using the web dev console; and to inspect what are the exact attributes of your link, in particular, the “target” attribute.
Often, you cannot see these DOM attributes directly reading the source code (these attributes can exist in the DOM but not in source), and so you will need to query the DOM to get the attributes (to be 100% certain).
Hope this makes sense.
