[Replay Details] Seeking to the first segment does not work

[billyvg]

Example Replay

The first segment is portrait, the 2nd is landscape. Let it play until it changes to landscape, then try to seek somewhere < 5 seconds, notice that the it remains in landscape. Seeking to :00 will rotate it back to portrait.

i tracked it down to findVideoSegmentIndex in utils.tsx returning the wrong segment index (it was returning 1 instead of 0 which is why the wrong segment was loaded when you seek), so i console logged trackList to see what was going on.

it looks like the first 2 + last 2 attachments have the same exact timestamp, which is why it was getting confused:

so i don't think it's the code, but rather something weird happened with the attachment timestamps -- seeking works normally with other replays with proper timestamps:

@michellewzhang good catch, I'm going to guess @romtsn was testing something and we got bad data. Don't think we need the UI to handle this type of bad data.
