[WEBSITE] Editing multiple keys at the same time leads to no response.

If you've 2 or more keys and click edit on the lower one, than the one above it, so both open, if you click edit again the keys disappear but the page becomes slightly unresponsive and you can't edit your keys.

A reload resolves this.

Start by reproducing the reported sequence in the website using Google Chrome: open two or more key editors, edit the lower key, edit the one above it, then click Edit again. Done means the keys remain available for editing and the page stays responsive without requiring a reload.
