[web-shared] Minor perf hardening to minimize renders by karthikscale3 · Pull Request #1104 · vercel/workflow

karthikscale3 · 2026-02-18T01:34:23Z

What the change does

Adds a size memo (prevSizeRef) so setSize only dispatches when width/height actually changed.
Adds a timing-change detector (didChange) so live updates do not dispatch forceRender unless root/span timing changed.

Net effect: reduces redundant renders/dispatches in timeline + resize flows, likely improving perf during live traces.
