Cannot set page value using the Confluence Page Gadget in JIRA

(Edited for clarity)

Adding the page gadget to a dashboard in JIRA, it is impossible to select a Confluence page. When starting to type in the Page field, suggestions do come up, but when you click on them you are automatically redirected to the actual page. There is no way to get it to populate the field. Typing it manually results in no page being selected.

Reproducible in all browsers: Firefox, Chrome, and IE.
