We have inherited the maintenance of a 10+ year old website which has a few links in it that force the link to be opened in the current tab. You can't right click on the link and open in new tab, or even copy and paste the url, because it uses javascript and a doPostBack (no idea why, old, old code).
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?
Much appreciated.
