Merge in work-in-progress for WTD-615 (Fixed Position View)
into topic branch for WTD-889 (a sub-issue of WTD-615, which
has been broken down into discrete chunks to support
development.
Conflicts:
platform/telemetry/src/TelemetrySubscription.js
Remove unused container definition for split pane; this
turned out not to be a suitable quick-fix approach to
WTD-747 (implementation of this behavior directly from
the browse template turned out to be more convenient.)
Restrict actions which cause mutation of domain objects to
types of domain objects which can be created. (This does not
include Packet or Telemetry Point, WTD-723.)
Add tests for capabilities which have been updated to work
when only a model (and not whole objects) are cached; that
change was introduced to prevent misbehavior of the Remove
action in Edit mode, WTD-473.
Utilize model cache, permitting object models in edit mode to
be reused across multiple distinct instances with unique
contexts (unique contexts are necessary to avoid ambiguity in
the Remove action, WTD-473).
To avoid infinite digest cycles as a consequence of this,
refactor context/composition capability wrappers such that the
former is idempotent (since idempotence is no longer ensured
by the EditableDomainObjectCache) to avoid infinite digest
errors in Edit mode.
Implement a cache to store domain object models,
to allow the cache for individual objects to distinguish
objects based on their parentage and avoid ambiguous
Remove actions (WTD-473.)
Add a spec for an editable model cache; this will behave
similarly to the existing domain object cache, except
that it will cache only models. Use of this will permit
multiple instances of editable objects to be created with
unique contexts (that is, distinct parent objects accessible
via the context capability) which in turn will avoid the
ambiguous parentage which results in unexpected behavior of
the Remove action in Edit mode, WTD-473.
Add tests to verify that directives stop polling after their
scope is destroyed (to prevent resource leaks); those changes
address resource leaks identified in the context of WTD-717.
Deactive mct-resize when its containing scope is destroyed;
that is, don't go on polling for size changes indefinitely.
Issue discovered/addressed in the context of investigating
sluggishness of plotting in WTD-717.
Add tests and JSDoc to the style sheet loader introduced to
allow bundles to introduce their own CSS files through the
platform's regular extension mechanism; WTD-591.
Update tests for dialog/overlay services to match
changes introduced to simplify implementation of
information overlays, such as the About dialog, WTD-667.
