After https://github.com/matomo-org/matomo/pull/12780 is merged most links will have
noopener noreferrer. To make sure all links now & in the future have this link, we should add a check to the UI test system:
noopener noreferrer, report an error and fail the test.
Instead there could be also a JS that runs onDomReady, onDomLoad and when components are updated through angular or so to check for any outgoing link in the modified dom and set it dynamically.
Since browsers now set
noopener by default we could close this issue I suppose. It be mostly something for IE11.
Also we could be sending a
Cross-Origin-Opener-Policy header. However, probably most of the browsers that support this header also apply noopener by default.
