Web: onLinkPress swallows cmd/ctrl/shift-click, so links can't open in a new tab #1084

Version: react-native-enriched-markdown 1.1.1

When onLinkPress is set, LinkRenderer calls event.preventDefault() and onLinkPress for every click. The docs recommend onLinkPress for in-app navigation, since target isn't configurable on web, but then cmd/ctrl-click (open in new tab) and shift-click (new window) stop working. Users lose standard browser behaviour on what are real <a href> links. (Middle-click is unaffected, since it fires auxclick, not click.)

Suggested fix: follow the convention web routers use (React Navigation's useLinkProps, React Router's and Next.js's Link): handle only plain primary clicks, and leave modified clicks to the browser. Links the browser can't open, such as custom-scheme mentions (user://…), keep going to onLinkPress:

const BROWSER_SCHEME = /^(https?:|mailto:|\/|#|\?)/i;

const handleClick = (event: MouseEvent) => {
  const isModified = event.metaKey || event.ctrlKey || event.shiftKey || event.altKey || event.button !== 0;
  if (isModified && BROWSER_SCHEME.test(url)) {
    return; // the browser opens it as it would any link
  }
  if (callbacks.onLinkPress) {
    event.preventDefault();
    callbacks.onLinkPress({ url });
  }
};

This needs no new API. Plain clicks behave exactly as today.
