Importing chapters shifts all labels "up" one and ignores final chapter

[DashingDave]

The fewer issues I have to read, the more new features I will have time to implement, so I ask that you please try these things first

• Try with the newest version from GitHub (also it might have already been fixed in latest nightly build)
• Read the documentation and FAQ, Known issues, Troubleshooting
• Search for your problem under Issues or Discussions
• This problem happens with all kinds of files that I try. For problem only with a particular file or type, use this other form instead

Operating System

MacOS 15

Steps to reproduce

1. Toggle "Ask about importing chapters from opened file" option to ON position
2. Drag a movie file (in my case, an .m4v) into LLC and choose "Import Chapters"

Expected behavior

As a simplified example, if the chapter listings in a 3-minute long video are
"Monday" 0:00
"Tuesday" 0:48
"Wednesday" 1:22
"Thursday" 2:01
"Friday" 2:31

then LLC would produce the following segments:
"Monday" 0:00 - 0:48
"Tuesday" 0:48 - 1:22
"Wednesday" 1:22 - 2:01
"Thursday" 2:01 - 2:31
"Friday" 2:31 - 3:00

Actual behavior

Continuing with the previous example, where the chapters in the 3-minute video are
"Monday" 0:00
"Tuesday" 0:48
"Wednesday" 1:22
"Thursday" 2:01
"Friday" 2:31

then LLC produces the following segments:
"Tuesday" 0:00 - 0:48
"Wednesday" 0:48 - 1:22
"Thursday" 1:22 - 2:01
"Friday" 2:01 - 3:00

Share log from developer tools

(The issue appears to be that LLC is designating the first segment/chapter to start at a negative time value.)
