Current search index changing when new lines are written

I began using the search addon to benefit from the newly implemented onDidChangeResults which allows us to get the currently highlighted match out of the total number of matches. The only thing that I'm wondering is why this line is being called as it causes this behaviour:

For context I'm watching a stress-test Docker container which writes a lot of new lines and I'm pressing the Enter key which calls the search addon's findNext method. With that line, the current index get constantly overwritten with the total size of results? I'm a bit confused if I'm doing something wrong, if adding lines in the middle of a search might break this? Let me know if you need more information.

Details

• Browser and browser version: Electron 17.2.0
• OS version: macOS Monterey 12.4
• xterm.js version: 4.19.0

Steps to reproduce

Created a sandbox to demonstrate what I'm saying. Even though the findNext is correctly highlighting the next match, the X of Y is constantly incorrect.
