[hawtio] If you triple-click an property, the console UI becomes unresponsive until page refresh

See video capture at https://youtu.be/KTYXnUOJu3A

Before the tripleclick, the page responds to cursor (there is the hover effect on links). After tripleclicking on one of the links, page stops responding completely (links cannot be clicked, text cannot be highlighted, ...) until the page is reloaded.
