Clicking on exclamation mark beside a variant name opens edit dialog, should open list of failed requests

When a request fails, it is added to "warnings" and also an exclamation mark is added to the variants list beside the variant that failed the request. When the mark is clicked, it opens dialog for editing the variant. The only way the user will be able to figure out what that exclamation mark means is to wait long enough so that the label appears (which takes kinda long time so the user might not expect it).
The proper way would be to open list of failed requests for this particular variant.
