The text field with the hasMany option enabled is not compatible with CJK IME input

[rktyt]

Describe the Bug.

The handling of Tab and Enter key presses is inadequate, resulting in unintended behavior.

I'm using Google's Japanese Input Method Editor (IME) available at https://www.google.co.jp/ime/ for text input.
In Chrome 136.0.7103.114, pressing the Enter key while using Japanese input causes the input value to be duplicated like this.

When the Tab key is pressed, it is supposed to select a conversion candidate, but instead, the input is being confirmed as shown below.

Note: The behavior may differ depending on the browser. As for Firefox, it is currently working as expected.

Reproduction Steps

fields: [
  {
    name: 'options',
    label: '選択肢',
    type: 'text',
    hasMany: true,
    localized: true,
  },
]

And use an IME for CJK input.
