LRC Lyrics ms (.lrc) rounding issue, discarded empty lines and improper use of the ti: tag #9048

I've tried to fix the timestamps in the LRC milliseconds format here: https://github.com/SubtitleEdit/subtitleedit/releases/download/4.0.8/SubtitleEditBeta.zip In Options - Settings, you can set the max duration to something higher, to avoid cutting lines at 8 seconds: |

The rounding error seems to be gone, but it seems to have broken the automatic setting of end times a bit. Opening this lrc file and then saving it as LRC Lyrics ms (.lrc) introduces empty lines when there's a duration above 8s, but does not set the end time 8s after the first timestamp (instead after 1933ms for the second timestamp): When changing the max duration to 30s in SubtitleEdit, these problems go away. However all the empty lines are removed in this case. Even the valid ones at [00:34.42], [00:53.04], [01:34.26] and [01:58.55] from the original file. Also even setting the max duration to 30s is often not enough as there are songs with huge instrumental parts (sometimes 5+ minutes before the singing resumes). To really make it work for lrc files, I'd have to set a value so high that it renders it useless for normal subtitles. |

I could make a new format |

That should eliminate the being turned into: |
Opening this .lrc file in SubtitleEdit and saving it with
LRC Lyrics ms (.lrc)as the format without performing any changeyields these rounded timestamps:
SubtitleEdit seems to also assume the max line duration to be 8s, (which for this song for example is too short). This cuts lines short and inserts empty lines within the lyrics.
Saving the initial file (without changing anything) as
LRC Lyrics, no end time (.lrc)on the other hand simply removes all empty lines:One might argue that the empty line timestamps in the initial file are invalid (2 lines start with the same timestamp), but they're from Deezer and fairly common. However SubtitleEdit also ignores valid empty lines like this one from another song that contains a passage without singing:
At least the second case should retain the empty lines.
On another note:
According to the wikipedia page,
tiis supposed to contain the song title, not the filename without extension, so setting it to this automatically is problematic as well.After fixing the timings in SubtitleEdit, adding back the passages without singing and saving the result as
LRC Lyrics, no end time (.lrc), it correctly saves these empty lines. But when reopening the file, they are gone again.Ideally I'd like SubtitleEdit to open the .lrc files while retaining (valid) empty lines and save the result after syncing without end timestamps but with ms precision (and without setting the filename as ti).
