String not added when in a list

[paulinebessoles]

Description

When trying to add a translation key with a list in it, I encounter intermittent issues when clicking on the autocomplete proposed string:

• the string is not added to the list
• a different translation key is added to the list

To reproduce

1. Go inside a translation set
2. Click on "Add multiple translations" button
3. Search for the string "Review the c"
4. With your mouse, click quickly on the autocomplete solution proposed for decidim.initiatives.create_initiative.fill_data.fill_data_help
5. See error

If you don't reproduce it the first time, try multiple times and you should encounter the error.

As this is hard to reproduce, here's a Loom video:

I have an error in console:

Additional information:

I was able to add the translation key at the end, so I don't think it's a big issue but just wanted to report it if someone encounter it also.
