Snippet lost if errors are present

Hi, thank you for this nice plugin.
I found a defect for me and is that if I create a snippet, switch the toggle to activate and save and an error is generated the snippet is lost. Going back on the browser never help to recovery it.

Also WordPress send an email of fatal error. Could you not improve the plugin behavior in the case of a problematic snippet that has a code issue avoiding loosing all code and maybe avoid WordPress send a recovery email? I’m migrating from another snippet plugin that if I was not wrong, never do if the code i wrong, it imply alert you with an error message in the admin backend without change page and made your code lost.

Thank you
