- In betalabs log in and switch to monobook skin.
- On RC page, click in the 'Active filter' area and click (set a check mark in the box) for a filter(s).
The selected filter will become selected and appears in the 'Active filters' area.
- Try to de-select the filter - the checkmark from the box cannot be cleared.
The screenshot shows the active state of the checkmark when a filter is selected (a separate issue with checkmark for highlighting was filed T165444: [betalabs-regression] monobook: Highlight button displays checkmark)
This screenshot shows inactive state of the previously selected filter - the filter was de-selected. The active filter area is cleared, but the checkmark is still present.
