Hi all,
Found a quirky bug here, was originally on 8.2 so upgraded to 8.2.1 and found the same problem too.
Relatively easy to produce. Open a PDF, open search (Ctrl+F), enter space into the search bar.
This will then often crash the browser, or at the very least stop the page from running.
Occasionally also occurs when searching for a phrase, e.g. “only office” where when you type the space between only and office, the search (and page) stops responding.
Nothing in browser console.
Replicable in both Chrome and Edge.
Hope this can be resolved in the next update. Any questions, or problems replicating, please do reach out!
