FLUID-4890: Diagnostics on attempting to access destroyed components - this causes numerous failures in test cases - in particular, any test which creates a preferences panel UI, and the pager's tooltips
FLUID-5293: Added a unit test to demonstrate FLUID-5293 issue.
FLUID-5293: Fix for failure in model relay through proper aliasing of "input" and "value" and their paths. We should review whether we really want this ambiguity in the framework.
Merge branch 'master' into FLUID-5293-antranig
FLUID-5293: Enhanced the unit test for FLUID-5293 to show another issue that, if the relay target is an array and the transformation is to remove element(s) from this array, the removal doesn't happen.

FLUID-5293: Fix for "mouse droppings in array" ChangeApplier issues
FLUID-5293: Reactivating tests that got forgotten during array work
FLUID-5293: Added into the unit test for FLUID-5293 to show another issue that the change request on the model array element is not properly relayed to the target component.
FLOE-5293: Modified the unit test to show the problem that firstly happens with the intermediary relay.

FLUID-5293: Fixes to model relay system to deal with relay from simple to compound values. i) disabled "link count" system for inhibiting relay (see FLUID-5303) and fixed resulting failure with "deltaMap" which returned {} interpreted as registering changes when none occurred

FLUID-5299: Work in progress to fix container height with long instructions.
FLUID-5314: Styling tweaks to make the overviewPanel look consistent across integrations.
FLUID-5314: Fixed width and height so toggle looks proper in Safari.

FLUID-5299: OverviewPanel now stretches to use vertical space.
- Panel now stretches to use all available space.
- When vertical space is reduced, a scrollbar appears when
necessary to scroll the instructions.
- This solution uses absolute positioning and fixed heights.
In some integrations, the fixed height and positioning needs
to be adjusted to fit the particular application.
