Defining a behavior on hover means making it different for people using
a keyboard or a touchscreen (most of the population, nowadays).
In this case, we had an accessibility issue where the message wouldn't
disappear once it appeared. That meant that, after tabbing through all
the links and buttons in, for instance, the debates index, the page
would be filled with "participation not allowed" messages, and in order
to see the information about how many people have voted, reloading the
page was required.
For touchscreen users the behavior was similar to what we get on hover,
although we've found some inconsistencies when trying to support several
elements on the same page.
We think in proposals it makes sense to hide the "support" button when
users click on it, and the same applies to the buttonsto support and
vote investment projects. However, we aren't hiding the buttons to
agree/disagree with a debate in order to keep the information about the
current number of people agreeing and disagreeing visible.
Note we're removing some support spec methods because after these
changes the duplication isn't as obvious as it was in the past.
This way blind screen reader users will know which proposal they're
supporting. In a list of proposals, context might not be clear when a
link saying "Support" or "Support this proposal" is announced, but a
link saying "Support Create a monthly transport ticket" is less
ambiguous.
Just like we did with investments in commit de436e33a, we're keeping the
title attribute because when visiting a proposal page, the connection
between the "Support" link and the proposal is not as clear as it is in
the proposals index page, so it might not be clear what you're
supporting.
This way we can make the view code a bit easier to read.
We're also changing the order of the conditions a little bit so we only
check for the presence of a current user once.
To make sure we aren't breaking anything with these changes, we're
adding some tests. We're also replacing one system test checking content
with a component test, since component tests are much faster.
