Anyway, I know it's poor user experience, as it's essentially a list of results and you would definitely want to open them in new tabs, also it's crazy to try and stop default browser behaviour.
But I'm wondering if there is anything specific in WCAG2.0 that says that we can't be doing this? I'm trying to make a case to have it changed, but poor UX won't be enough. WCAG however will get it over the line. Is anyone able to point me to anything in the web content accessibility guidelines that explicitly says that a website shouldn't do that?
