Describe the bug
Keyboard navigation of filter widgets. After going to desired widget, pressing the "Down Arrow" key moves the user into the filter options. But the user is no longer able to go back to the widget header and close the widget once opened, by using the arrow keys. Press "Tab" will move the focus to the next widget as well as "Shift + Tab" will move focus back to the previous widget. While using either method to go back to the opened widget header, the focus moves into the filter options.

To Reproduce
Detailed steps to reproduce the behavior:

1. Tab to filters
2. Press "Enter" to open widget
3. Press "Down Arrow" to go into options
4. Neither pressing "Up Arrow" will not bring focus back up to Widget header. Nor pressing "Down Arrow" will loop back up to Widget header.
5. Pressing "Tab" or "Shift + Tab" will move focus away from opened widget. But using pressing "Tab" or "Shift + Tab" to go back to the open widget, will open move focus back into the opened widgets filter options

Expected behavior
There should be a way for keyboard users to be able to close the opened widget. Once widget is opened the user should be able to "Tab" back to the header of the opened widget to close.
