Avoid proofreading actions while the last one is not finished

 - The Layers tab now displays an Add Skeleton Annotation Layer button with which volume-only annotations can be converted to hybrid annotations. [#6330](https://github.com/scalableminds/webknossos/pull/6330)
 
 ### Fixed
+- Fixed an error if multiple proofreading actions were performed in rapid succession. If webKnossos is busy, inputs to the viewports are disabled from now on. [#6325](https://github.com/scalableminds/webknossos/pull/6325)
 
 ### Removed
 - Annotation Type was removed from the info tab. [#6330](https://github.com/scalableminds/webknossos/pull/6330)
