When selecting characters in Chinese and Japanese IME, the search function may be triggered incorrectly.

[PhantasWeng]

Description

In Chinese and Japanese input methods, character selection is done using pinyin and enter key.

For example: to input "你" (ㄋ一ˇ), you would type ㄋ + ㄧ + ˇ + enter to select the character.
Currently, pressing enter triggers an incorrect input.

This results in submitting ㄋ一ˇ instead of 你.

Steps to reproduce

1. Go to DocSearchModal > input
2. Keypress on ㄋ一ˇ enter (key mapping to su3 enter)
3. Expected to be a character selection, but turned into link selection.

Expected behavior

Expected to be a character selection on first enter keypress.

For example, in chrome url input

In github text area

Environment

• OS: [e.g. macOS]
• Browser: [e.g. Chrome]
• DocSearch version: Algolia DocSearch for docusaurus
