Search button intercepts browser shortcuts when focused

[brc-dd]

Description

See facebook/docusaurus#11725

Steps to reproduce

1. Go to https://docusaurus.io/
2. Focus the search button
3. Press Cmd+Opt+I
4. See Dead being set as initial query in the search modal.

Expected behavior

The browser devtools should open in that case.

This part will need modification -

docsearch/packages/docsearch-core/src/DocSearch.tsx

Lines 178 to 184 in 7c36039

	const onInput = React.useCallback(
	(event: KeyboardEvent): void => {
	setDocsearchState('modal-search');
	setInitialQuery(event.key);
	},
	[setDocsearchState, setInitialQuery],
	);

e.key is Dead in Chromium in certain cases (and likely in other browsers too according to MDN, but I wasn't able to reproduce).

It shouldn't intercept stuff when Ctrl or Cmd is held I guess. For example, if the search button is focussed and you try to do Cmd+R for reload, it opens the modal with r typed instead.

Environment

• OS: macOS 26.2
• Browser: Chromium 144.0.7559.96
