What
Makes the timing labels on the trace viewer timeline precise when zoomed in.
When the timeline is zoomed in far enough that the ruler's tick step drops below one second, the tick labels were formatted with whole-second precision. This produced duplicate, imprecise labels — e.g. a ~3s window with a 500ms step rendered
0s, 1s, 1s, 2s, 2s, 3sinstead of distinct values. This PR scales each label's decimal precision to the tick step so every tick reads accurately.Changes
