Description

Describe the bug

When I move mouse over "Timer" events in the Temporal UI, all "Timer" lines are highlighted at the same time:

Mouse over "Timer Started":
Image
Mouse over "Timer Fired":
Image

Looks like a bug, because the others don't do the same, e.g. "Workflow Task Scheduled"

To Reproduce
Steps to reproduce the behavior:

  1. Go to temporal ui
  2. Hover mouse over the lines

Expected behavior

Don't highlight them together?

Desktop (please complete the following information):

  • OS: MacOS
  • Browser Arc
  • Version 1.129
  • Tempora UI: 2.42.1

Additional context

JSON with these events, hope it helps

Research direction

Start in the Temporal UI history view, reproduce the hover behavior using the attached events JSON, and compare Timer Started/Timer Fired with Workflow Task Scheduled. Trace the history-event highlighting entry point and verify that hovering one Timer event highlights only its corresponding line, without changing highlighting for other event types.
