Screenshot timeline shows two thumbnails for the first frame when the capture starts

Steps to reproduce:

1. Create a new 3D URP project via Unity Hub
2. Open the Profiler (Window > Analysis > Profiler) with the Screenshots module shown, Game View open
3. Enter Play mode and record a capture from the start
4. Look at the front of the Screenshots timeline

Actual results: The front of the timeline shows two thumbnails both labelled 1 - the strip reads 1, 1, 16, 31, 46, ... instead of 1, 16, 31, 46, ... The duplicate is a separate entry, so the reported screenshot count is one higher than the number of distinct frames, and selecting frame 1 only ever resolves one of the two.

Expected results: The first frame should have a single thumbnail and the reported count should match the number of distinct captured frames.
