link using "a" tag with target _blank in MVC

Question

I'm trying to add a link in our MVC web site to an external website and I want to open it in a new tab.

Unfortunately, when I add target="_blank" to my link, it stops working.

Without it, it correctly opens in the same tab.

In a new created MVC app, no problem either.

Please, anyone has an idea what could be blocking this ?

thanks in advance.

Ok, the console message was not perfectly clear but I found it.

We have CSP rules, and I had to add 'allow-popups' to allow blank target...

Only a day and a half to find it...
