In regular system tests, we prefer testing against the text of the link
because it's easier to recognize which link we're talking about.
I was wondering whether we should remove the `title` attribute
completely and use just the `aria-label` attribute. Quoting The Paciello
Group blog [1]:
"If you want to hide content from mobile and tablet users as well as
assistive tech users and keyboard only users, use the title attribute."
However, there's a case where mouse users might find the title attribute
useful. When visiting an investment page, the connection between the
"Support" link and the investment is not as clear as it is in the
investments index page, so it might not be clear what you're supporting.
As mentioned, though, this information will only be relevant for mouse
users, who nowadays represent less than half of our users.
