demo/screen recording of the problem

Sometimes, when working with views that embed an SWT Browser control, switching between the views can cause the caret to be lost in the editor.

Steps to reproduce:
- Open a .java file
- Open the JavaDoc view + enable link-with-editor
- Switch between the JavaDoc view and the editor by clicking in them.
- Sooner or later the caret in the editor will vanish.

See attached a screen recording with a short demo.

The caret will re-appear once the editor area loses and gains focus again.

This seems to be a problem in the interaction between editor focus handling and Browser#setText(). Hence, not sure if SWT or UI would be the right component.

I could only reproduce this on Windows (with the IE browser engine).
