BUG: text dissapears when worksession is updated


I encountered very very unpleasant thing.

Follow these steps to reproduce.

  1. create any text in model space
  2. attach other model with different annotation styles
  3. change the text annotation style to one from the attached file
  4. change something in the attached file, save and update the reference in the model with text
    5. the text dissapeares once you update the attached file from which the style was taken
