System.InvalidOperationException after 'ESC' key

The following error occurs when attempting to open then to cancel it immediately with 'ESC' key a book card dialog window. This is a severe error, AEM will crash afterwards. Similar problems will occur for author or a tag dialog window, but AEM may not crash.
The scenario could be reproduced in Windows10 with a small database, actually with the latest AEM 5.9.0.0 default database.

ok, we reproduced the error. We'll try to fix it.
Hope, it's not critical, as it's not natural program use

It seems the issue is fixed in 5.9.5.0. As well the performance has been strongly improved. Great work!
