jaredg I installed the "Brave browser" to test if there was a specific issue with it, but I could not reproduce the behaviour that you are mentioning.
If it's sending a
POST request to the
delete endpoint, it means that for some reason the word appears as it's already added to the list. If I'm not missing something, this could only happen when a word is being added/removed from different tabs that are opened at the same time. Is that part of your workflow?
JapanDict is not open source. I prefer to keep the code of the site in a private repository for the moment. Thank you for the offer anyway. 😃
