User lost sight of the keyboard focus very often

The Dragon Naturally Speaking user reported frequent loss of keyboard focus while navigating our map application. Even though the focus indicator was present, it was not readily apparent to the user. The test facilitator had to constantly assist by pointing out the location of the keyboard focus.

This is a bug in how focus is managed withn the feature popup (aka button). The tab / shift+tab keys should move around the popup controls but never exit the popup. You should only exit the popup when you dismiss it or press next/previous buttons in the popup controls. However we noticed that focus drifts outside the popup by accident. For example, steps to reproduce:

Load this page
Tab to the first feature (tab x 2)
Hit enter to activate the popup
Tab x 1
Shift+Tab x 1
What you expect to happen: focus should be on the X (dismiss) button
What happens: focus returns to the feature, leaving the popup displayed
