Ctrl + Rightclick causes skeleton annotation corruption

[daniel-wer]

Context

I tried to use the Ctrl + Rightclick functionality to create nodes that won't be centered automatically.

Expected Behavior

A node should be created at the click location without centering it.

Current Behavior

The message "A corruption in the current skeleton annotation was detected. Please contact your supervisor and/or the maintainers of webKnossos to get help for restoring a working version. Please include as much details as possible about your past user interactions. This will be very helpful to investigate the source of this bug." appears.

Steps to Reproduce the bug

1. Create/Activate an empty tree
2. Use Ctrl + Rightclick to create a first node
3. Use Ctrl + Rightclick to create a second node
   -> The corruption message appears after a short time.
