Creating a new location copies the name in the text box each time you perform a keyboard action on the text box

[Novocastrian]

Describe the bug
As the title says, the text box seems to inject the text box name whenever you do a keyboard action that isn't entering a character, such as Delete and Return keys doing their intended action then duplicating the text box contents

To Reproduce
Steps to reproduce the behaviour:

1. Start a new Blaze Black 2 Redux nuzlocke
2. Click the ⋮ next to any location (e.g. next to Floccesy Ranch)
3. Click Add Location
4. Enter a new name for the location
5. Hit the Return key on the keyboard a few times
6. Place the cursor anywhere in the generated text and click, then hit the Delete key a few times
   Expected behaviour
   Return submits the name and changes the focus to the next element for keyboard/screenreader users.
   Delete deletes the character, and the focus remains inside the textbox.

Actual Behaviour
Return adds a new line then duplicates the entire textbox text.
Delete deletes the character then duplicates the entire textbox text.
