Description
I am using the standalone js provided on the home page (https://cdn.redoc.ly/redoc/v2.0.0/bundles/redoc.standalone.js).
I notice when searching with long query strings that have matching candidates, the ui becomes very slow and even completely stops responding or crashes. I'm using Chrome.
One thing I found is if I disable diacritics (looks like related to a certain type of regexp) in 'redoc.standalone.js' (by setting it to !1 instead of !0) the error disappears, and performance is significantly improved.
I cannot find diacritics in the codebase. So, I suppose it's from some library? Can you please advise if it's a known issue and if there's any solution for it? Please let me know if you require more clarification. Thank you.

Research direction
Reproduce the slowdown in Chrome using a long query with matching candidates against the standalone js bundle from the home page. Compare behavior with diacritics enabled and disabled, then trace where diacritics enters the bundle or its dependency. Done means the search remains responsive for the reported case and the fix is verified against a regression scenario.
