## Issue
Closes 5523: timestamps not interpreted in some cases
## Notes
`remark-breaks` previously kept repeating the same index in the loop, causing some corner-cases to be parsed oddly. I added code to address that.
Later, `remark-breaks` fixed the problem and we recently just bumped up the componnent version. My hack is no longer necesary.
## Issue
- The previous regex uses lookback (I think ES2018?) which Safari has yet to implement.
- There were a few bugs in the previous regex too, like missing out multiple timestamps in a line, or parsing "62:02" as "2:02" (although YT does this as well).
- The previous method searched too deep (matchAll) on each 'locate' call, which was wasteful.
