Hidden issue ID and tracker (display only on hover) - Issues panel plugin

[johnjeffersoncm]

When using purplemine with the issues panel plugin ( https://github.com/redmica/redmine_issues_panel ), the id and tracker of the cards are hidden, they are only shown if you hover the mouse over this field. This problem does not occur in other themes. I created a clean install of redmine in a new docker container, and installed just this plugin and this theme to make sure they were the cause of the bug.

In the print below you can see the problem.
