"Negate" Option for On-Demand Inactive After Initial Filter Operation

[wbedard]

Hardware/Software Used:
Nexus7 (stock 4.4.2, XP r64)

Steps taken to reproduce:
With "Restrict On Demand" enabled (a first for me...), use the filter capability to clear out all existing FOD settings. Enabled FOD filter and applied...list updated with all apps with FOD enabled.

After disabling FOD in those apps, attempted to modify filter to add "Negate" option to FOD filter. The negate control was disabled (greyed-out) and non-responsive.

Proceeded to clear FOD filter and apply...app list updated as expected.

Went back to filter and enabled FOD. Once FOD is checked, Negate option is enabled ( not greyed-out) and is responsive. After applying the filter and returning to the filter dialogue, the Negate option for FOD is disabled, regardless of the state of the FOD filter control. Toggling the FOD filter control does re-enable the negate option, where it responds as expected.
