DYN-10081: Preserve warnings/info stack format and Batch node info updates#16955
Conversation
Prevent transient warnings/errors from being cleared when restoring node State during Info() by adding a suppressTransientClear flag and scoping State assignments. Adjust ClearInfoMessages so only info-related states are promoted back to Active and other states (Warning/Error) keep their state while still removing info entries. Add batching to InfoBubble/NodeViewModel updates (BeginBatchUpdate/EndBatchUpdate and dispatcher invocation) to avoid repeated RefreshNodeInformationalStateDisplay calls and duplicate subscriptions/Workspace error entries. Minor fixes: tighten GetHashCode parentheses and add Clear() to ObservableHashSet. Overall: correctness (preserve warnings) and performance (batch updates, avoid double-subscribe).

Pull request overview
Fixes and improves the node “bubble” messaging system so Info and Warning/Error bubbles can coexist (stacked) on non-chart nodes, while also reducing redundant UI refresh work during message updates.
Changes:
- Prevents
NodeModel.Info()state restoration from clearing transient warnings/errors, allowing Warning+Info to coexist inInfos. - Adds batching to suppress per-item
RefreshNodeInformationalStateDisplay()rebuilds duringNodeMessagesupdates. - Improves bubble lifecycle/subscription handling and fixes
Info.GetHashCode()operator precedence.

This confusing naming has been there for a while. We have a notion of Info vs Warning messages, but we still maintain a type with the same conflicting name, "Info", that actually can be any type of message, even warning or error.

Is this a good time to rename some of these fields/properties to something more sensible and have a clear separation of meaning?

Some minor comments and questions, then LGTM!
Rename the private boolean suppressTransientClear to suppressClearTransientMessages in NodeModel and update all references accordingly. The flag is used to suppress clearing transient warnings/errors during state/Info restoration. Also remove the public Clear() method from ObservableHashSet<T> (and its Reset event invocation), so the collection no longer exposes a Clear API.

Purpose
TL;DR
Fixes a bug where Info and Warning bubbles couldn't coexist on non-chart nodes (info would silently wipe the warning from the Infos collection), plus performance and lifecycle improvements to the bubble system.
Problem
Changes
What this enables
All three bubble sections (Error, Warning, Info) can now coexist on any node — not just chart nodes. The node's bottom bar reflects the highest-priority state, and the bubble stacks sections vertically: Errors (red) → Warnings (orange) → Info (blue).
