On click of a hyperlink open a VBCS page in a popup window from Oracle SaaS Page

Summary:

Till January 2024. Once I click on a hyperlink in Oracle SaaS Page a VBCS page opens up in popup window. It was working fine. From March 2024 we can see when we click on the hyperlink the VBCS Page opens up but in the same window closing the SaaS page instead of opening up in a popup. I want to check if anything changed in 24A release. 

In sandbox I was keeping this URL in hyperlink. 

<a href="<< VBCS Page URL>>" target="popup" onclick="window.open('<< VBCS Page URL>>','popup','width=900,height=900'); return false;"> Link Name </a>
