Last final line error: the timestamp extends till the end of the video file

[Excess-Code]

Subsync v0.17 (MacOS Sonoma)

Thank-you for all the hard work (love your program) but wanted to flag this persistent error

When syncing an srt file the timestamps on the final line are re-synced incorrectly. The timestamp starts at the correct moment but does not end correctly and instead extends till the end of the video files timestamp. This leads to the final subtitle line being displayed too long and persist on screen for the rest of the video.

The error does not happen in all cases but is persistent and annoying as each re-synced file needs to be double checked and hand edited to remove the error. It is unclear what parameters lead to this error but I can try and narrow down the options if you are looking into it.

Example....

Original srt file
1285
02:26:10,073 --> 02:26:12,483
This is only the beginning.

Synsync edited srt file
1285
02:26:54,073 --> 02:35:25,098
This is only the beginning.
