I've noticed that viewing an Agile Wallboard Gadget that makes use of a board's quick filter(s) can impact the appearance of the actual Agile board referenced by the gadget when you switch over to it. When you switch from the dashboard to the Agile board, the URL will use the filter settings that were applied to the gadget on the dashboard, BUT the corresponding filters do not have the visual cue that they are being applied. This results in an inverted behavior for those filter buttons (i.e. turning the filter 'on' actually turns it 'off').

So the problem is two-fold. First, the gadget's filter settings replace any user stored filter settings - a very minor inconvenience. Second, the behavior of those filters becomes inverted, which can be rather confusing for users.

The steps to reproduce this bug are:
1. Create an Agile board with some quick filters and create a dashboard that uses the Agile Wallboard Gadget, which is configured to apply at least one of those quick filters.
2. View the dashboard.
3. View the Agile board.
4. Compare the applied quick filters in the URL to which ones are applied visually in the UI.

This bug does not seem to occur 100% of the time, but does seem to occur the majority of the time.
