[js] link text TypeScript locator matches links that are not rendered #18215

The TypeScript link-text locator reads a link's text with innerText. For an element that is not rendered (for example display:none), innerText falls back to the text content. So a hidden link can match an exact or partial link-text search, and the caller can get a different element back. The Closure locator used bot.dom.getVisibleText, which returns an empty string for hidden elements.

This was already on trunk in javascript/atoms/typescript/find-elements.ts (innerText ?? textContent). #18175 moved it unchanged into core/locators.ts (getLinkText). Qodo raised it there: #18175 (comment)

Suggested fix: when the link is not shown, treat its text as empty, keeping the   normalisation and the trim. Add exact and partial link-text tests against a display:none link.
