Unable to label more than four regions in Audio

I am running into a strange issue with an audio transcription task I'm trying to complete. I am able to label four regions of my file without any issue, but as soon as I attempt to label a fifth I get an error and the following stack trace:

```

I noted a user in the Slack support channel experiencing a nearly identical problem with a video task (4 labels are fine, the fifth throws this error) so perhaps it's reproducible in other task types too: [Slack Support Thread](https://label-studio.slack.com/archives/CQ8LYQ0J2/p1716191107317229)

**To Reproduce**
Steps to reproduce the behavior:
1. Create new project
2. Use MP3 file and "perRegion" TextArea (my view code is above)
3. Label four regions in the file and enter transcripts
4. Label a fifth region and attempt to enter a transcript
- The error will occur before even submitting the new annotation, seemingly as the app attempts to process text from the fifth transcript

**Expected behavior**
More than four annotations on an audio file would work

**Environment (please complete the following information):**
- Label Studio Version 1.12.1
- Installed via PiP on Debian Linux 12.6 (fully updated), also tried the official Docker image
